I remember it like it was yesterday. It was a bustling Saturday morning at my local Costco, the kind where the aroma of hot dogs and samples of savory snacks filled the air. Sarah, a friend and fellow bulk-buying enthusiast, was at the checkout, her cart overflowing with industrial-sized peanut butter and enough paper towels to last a small army a year. She confidently handed over her shiny American Express credit card, the one with the distinctive Costco logo, only for the cashier to shake their head apologetically. “Sorry, ma’am,” they said, “we don’t take Amex anymore.” Sarah’s face, usually calm and collected, crumpled in confusion and a hint of frustration. “What do you mean you don’t take Amex? I’ve used this card here for years! It’s my Costco card!”
That scene, or a variation of it, played out countless times across the country, marking the end of a nearly two-decade-long, exclusive partnership that had become synonymous with shopping at the warehouse giant. For many, it was a sudden, jarring shift. So, why did Costco remove Amex? The succinct answer is primarily rooted in a protracted disagreement over interchange fees—the “swipe fees” merchants pay to process credit card transactions—with American Express charging higher rates than what Costco, a low-margin, high-volume retailer, was willing to continue paying. This financial friction, coupled with Costco’s desire for broader payment acceptance for its members and the strategic opportunity to secure a more favorable co-branded credit card agreement with Citigroup and Visa, ultimately led to the split in 2016.
The End of an Era: A Partnership’s Legacy and Its Undoing
For sixteen years, from 1999 to 2016, the relationship between Costco and American Express was an exclusive and, for many, an immensely convenient one. If you were a Costco member and wanted to pay with a credit card, your only option was an American Express card, specifically the co-branded “TrueEarnings” card. This card offered generous cash back rewards, particularly on gasoline and at Costco itself, making it a staple in the wallets of millions of loyal members. It wasn’t just a payment method; for many, it was *the* Costco card, an integral part of their membership.
During this period, American Express enjoyed unparalleled access to Costco’s incredibly loyal and high-spending member base. It was a mutually beneficial arrangement for a long time. Amex gained millions of cardholders and massive transaction volume, while Costco offered a premium co-branded card and, presumably, favorable terms on transaction processing fees compared to their standard rates. However, like many long-term relationships, challenges eventually arose, primarily centered around the financial structure underpinning the deal.
The exclusivity of the partnership, while convenient for the cardholders who adopted the Costco Amex, also led to a significant point of friction for others. Members who preferred Visa or Mastercard, or simply didn’t want another Amex card, were forced to pay with debit, cash, or check. This limitation, while perhaps a minor inconvenience for many, highlighted a potential constraint on Costco’s growth and customer satisfaction in the long run.
The Core of the Matter: The Unseen Costs of Interchange Fees
To truly understand why Costco and Amex parted ways, we need to talk about interchange fees. For most consumers, swiping a credit card is a seamless, cost-free transaction. But for merchants, it’s a significant operational expense. Interchange fees, often referred to as “swipe fees,” are the charges a merchant pays to a credit card issuer (like American Express, Visa, or Mastercard) every time a customer uses their card to make a purchase. These fees are typically a percentage of the transaction amount, plus a small flat fee.
Think of it this way: when you buy that giant bag of chips for $10 at Costco, a small portion—say, 1.5% to 3.5%—doesn’t go to Costco. It goes to your card’s issuing bank and the payment network. For a business like Costco, which operates on notoriously thin profit margins (often in the low single digits), these fees represent a massive chunk of their operating costs. When you’re dealing with billions of dollars in annual sales, even a fraction of a percentage point difference in interchange fees can translate into hundreds of millions of dollars.
- Understanding Interchange Fees:
- Paid by the merchant to the card-issuing bank.
- Typically a percentage of the transaction amount + a flat fee.
- Varies based on card type (rewards cards often have higher fees), transaction type (online vs. in-store), and merchant category.
- The Impact on Retailers:
- A significant operating expense, especially for high-volume businesses.
- Directly impacts profit margins.
- Influences pricing strategies for goods and services.
American Express, historically, has operated on a different business model than Visa and Mastercard. Unlike Visa and Mastercard, which primarily act as payment networks and don’t typically issue cards themselves (instead partnering with banks that do), American Express is both a network and a major card issuer. This integrated model often allowed Amex to charge higher merchant fees, which they argued were justified by the higher-spending, more affluent customer base they brought to merchants. For many small businesses and premium retailers, accepting Amex was a status symbol and a way to attract these valuable customers.
However, for a warehouse club like Costco, with its fundamental business model built on volume and razor-thin margins, these higher fees became an increasingly painful pinch. Every dollar spent on interchange fees was a dollar that couldn’t be passed back to members in the form of lower prices or better value, which is Costco’s core promise.
Seeking Better Terms: The Negotiation Breakdown
The relationship between Costco and Amex began to fray publicly around 2014-2015 when their exclusive agreement was up for renewal. Costco, acutely aware of the financial burden of interchange fees and emboldened by its massive market presence, entered negotiations seeking significantly lower rates. They had immense leverage: millions of loyal customers, staggering sales volumes, and a strong brand.
Costco’s argument was straightforward: their business model, focused on high volume and low prices, simply could not sustain Amex’s fee structure. They needed a deal that aligned with their operational realities. They likely pointed to industry trends where Visa and Mastercard, under increasing pressure and competition, were often willing to offer more competitive rates, especially to large-scale merchants like Costco.
American Express, for its part, faced a tough decision. Lowering their fees to Costco’s desired levels would not only impact their own profitability but could also set a precedent, potentially leading other large merchants to demand similar concessions. Amex might have believed that its brand prestige and the value of its cardmember base—who often spend more—justified their fee structure. They likely also considered the sheer volume of their cards being used at Costco, which represented a significant portion of their overall network volume. Giving up such a massive exclusive deal would be a huge blow.
Ultimately, the two giants simply could not agree on terms. The negotiation broke down. Costco, always prioritizing its members and its value proposition, made the strategic decision to walk away from the table and seek a new partner. It was a bold move, severing ties with a partner they’d had for nearly two decades, but it underscored Costco’s unwavering commitment to its business model.
The Allure of Visa and Citi: A New Beginning
Once the decision was made to part ways with American Express, Costco began a new search for a payment processing network and an issuing bank for its co-branded credit card. The choice ultimately fell to Visa as the exclusive network and Citigroup as the new issuer of the co-branded card. This wasn’t a casual decision; it was a calculated strategic shift that promised several key advantages for Costco and its members.
Why Visa? Broader Acceptance, Lower Fees
The move to Visa offered an immediate and substantial benefit: near-universal acceptance. While Amex is widely accepted, Visa boasts an even broader global acceptance network. This meant that any Visa credit card could now be used at Costco warehouses across the United States. For members who didn’t want another credit card, or preferred to use a different Visa card they already had, this was a massive win. It eliminated the long-standing frustration of Amex being the *only* credit card option.
More critically, Visa’s interchange fees were generally more competitive and aligned better with Costco’s low-margin business model. By switching to Visa, Costco could significantly reduce its transaction processing costs, potentially saving millions, if not hundreds of millions, of dollars annually. These savings could then be reinvested into keeping membership fees low, offering better product pricing, or enhancing other member benefits, thereby reinforcing Costco’s core value proposition.
Why Citigroup? A Major Player for a Major Partner
To replace the co-branded “TrueEarnings” Amex card, Costco partnered with Citigroup (Citi) to issue the new Costco Anywhere Visa Card. Citi is one of the largest credit card issuers in the world, with extensive experience managing large-scale credit card portfolios and loyalty programs. This made them a natural fit for handling Costco’s enormous member base and the transition of millions of cardholders.
The new Citi Visa Anywhere Card was designed to be highly competitive, offering robust cash back rewards that, in many categories, surpassed what the old Amex card provided. The new card’s features included:
- 4% cash back on eligible gas and EV charging purchases (up to $7,000 per year, then 1%)
- 3% cash back on restaurants and eligible travel purchases
- 2% cash back on all Costco and Costco.com purchases
- 1% cash back on all other purchases
These reward categories were compelling, especially the 2% back on all Costco purchases, which was a direct benefit for loyal shoppers. Furthermore, the fact that it was a Visa card meant that the card itself could be used virtually anywhere Visa is accepted, not just at Costco, adding to its utility and appeal.
The transition process, while complex, was handled relatively smoothly. Existing Costco Amex cardholders received new Citi Visa cards automatically, usually with their credit history and account details transferred, minimizing disruption for many. This seamless transition was a crucial element in maintaining member satisfaction during such a significant change.
Impact on Shoppers: The Good, The Bad, and The Bewildering
For millions of Costco members, the news of the Amex split was met with a mix of reactions, ranging from relief to outright dismay. As a shopper myself, I certainly heard plenty of chatter in the aisles, with people debating the pros and cons.
Initial Shock and Disappointment
Long-time Costco Amex cardholders, like my friend Sarah, often felt a sense of betrayal or at least significant inconvenience. They had built their reward strategies around the Amex card, and for many, it was their primary card for everyday spending, not just at Costco. The thought of having to get a new card, update automatic payments, and potentially lose accumulated rewards was frustrating. Some preferred Amex’s customer service or specific benefits that they had come to rely on.
“I had the Costco Amex for over a decade. It was the only card I really needed for gas and my Costco runs. When they switched, it felt like an old friend just disappeared. I had to rethink my whole spending strategy.” – A quote encapsulating common member sentiment during the transition.
Adjusting to the New Reality
Once the dust settled, however, many members began to appreciate the new arrangement. The ability to use *any* Visa credit card at Costco was a huge practical improvement for many. No longer were they forced into an exclusive payment method. This brought Costco in line with most other major retailers, offering greater flexibility at the checkout lane.
The Citi Visa Anywhere Card also proved to be a strong contender in the rewards landscape. The enhanced cash back categories, particularly for gas, travel, and dining, often made it a more lucrative card for a broader range of spending, not just within Costco. For example, the 4% cash back on gas was a particularly strong draw, especially for those with long commutes or larger vehicles.
Here’s a simplified comparison of the typical rewards structure (note: actual rewards can vary by specific card versions and terms over time):
| Reward Category | Old Costco TrueEarnings Amex (Approx.) | New Costco Anywhere Visa by Citi (Approx.) |
|---|---|---|
| Gas/EV Charging | 3% | 4% (up to $7k/year) |
| Restaurants | 1% | 3% |
| Travel | 1% | 3% |
| Costco & Costco.com | 2% | 2% |
| All Other Purchases | 1% | 1% |
| Acceptance at Costco | Exclusive (only Amex) | Any Visa credit card |
| Acceptance Outside Costco | Where Amex is accepted | Where Visa is accepted (much broader) |
This table illustrates why, for many, the new card was objectively a better deal in terms of raw reward percentages and overall utility.
The Business Strategy Behind the Split
Costco’s decision to switch from Amex to Visa and Citi was a masterclass in strategic business maneuvering, underscoring its relentless focus on value for its members and its own bottom line.
Costco’s Focus on Value: A Core Principle
Costco operates on the premise of offering high-quality goods at the lowest possible prices. Its entire business model—from selling in bulk to negotiating aggressively with suppliers—is geared towards this. High interchange fees directly contradict this philosophy. By switching to a network with lower fees, Costco could either realize significant cost savings or pass those savings on to members, further cementing its reputation as a value leader. This move wasn’t just about saving money; it was about protecting and reinforcing the very essence of the Costco brand.
Increased Member Satisfaction (Eventually)
While the initial transition caused some member consternation, the long-term benefits of the switch generally led to increased satisfaction. The broader acceptance of *any* Visa card made shopping at Costco more convenient for a larger segment of its membership. Furthermore, the enhanced rewards of the new co-branded Citi Visa card provided a more compelling value proposition for many members, both inside and outside the warehouse.
Costco understood that while some members might be initially upset, the long-term benefits of lower costs and better payment flexibility would ultimately outweigh the short-term inconvenience. This decision showcased a willingness to make tough choices for the greater good of the company and its membership.
Financial Gains for Costco
The exact financial impact for Costco isn’t always publicly disclosed, but it’s widely believed that the switch resulted in substantial savings. Industry analysts estimated that Costco could save anywhere from tens of millions to hundreds of millions of dollars annually by reducing transaction processing costs. Given Costco’s massive transaction volume, even a small reduction in the percentage of each swipe fee adds up to a staggering sum over a year.
These savings contribute directly to Costco’s profitability, allowing them to maintain their competitive pricing structure and potentially even invest in other areas of the business, such as expanding product offerings or improving warehouse facilities. It was a clear financial win for the company.
Amex’s Loss: A Significant Blow
For American Express, losing the exclusive Costco partnership was a significant blow. They lost millions of co-branded cardholders and a massive volume of transactions. Costco was, at one point, responsible for about 10% of Amex’s total billed business. The loss of this partnership certainly impacted Amex’s stock price and required them to re-strategize their card acquisition and retention efforts. They worked diligently to convert former Costco Amex cardholders to other Amex products, offering incentives to retain their business.
A Deeper Look: The Dynamics of Co-branded Cards
The Costco-Amex split provides a fascinating case study in the complex world of co-branded credit cards. These cards are a powerful tool for both retailers and financial institutions, but they come with inherent risks and challenges.
What Makes a Co-branded Card Successful?
A successful co-branded card thrives on a symbiotic relationship between three key players: the retailer (Costco), the card network (Visa/Amex), and the issuing bank (Citi/Amex). Each party brings something to the table:
- Retailer: Brings a loyal customer base, brand recognition, and a platform for card usage. They benefit from increased customer loyalty, data insights, and often a share of interchange revenue or other financial incentives from the bank.
- Card Network: Provides the infrastructure for transactions, security, and global acceptance. They benefit from increased transaction volume and brand visibility.
- Issuing Bank: Manages the credit risk, customer service, and marketing of the card. They benefit from interest income, annual fees (if any), and interchange revenue.
The “sweet spot” is when the benefits for all three parties are aligned and mutually sustainable. When one party feels the scales are tipping too much in favor of another, as Costco felt with Amex’s interchange fees, the partnership becomes vulnerable.
How Costco Used This Relationship to Its Strategic Advantage
Costco skillfully leveraged its unique position—a membership-based retailer with incredibly high sales volume and a fiercely loyal customer base—to secure highly favorable terms. By playing Visa and Citi against other potential partners, Costco was able to negotiate a deal that not only lowered its operating costs but also provided a significantly improved product for its members. This strategic move demonstrated the immense power of a major retailer in the payment ecosystem, capable of influencing the terms and conditions of global financial giants.
Lessons Learned from the Split
The Costco-Amex breakup offered valuable insights for various stakeholders:
- For Retailers: The Power of Negotiation. Costco’s willingness to walk away from a long-standing, exclusive deal showed that even the biggest players in the payment industry are not untouchable. Retailers with significant transaction volume have considerable leverage to demand better terms.
- For Card Networks: The Importance of Competitive Pricing. Amex’s historical premium fee structure, while successful in certain segments, proved unsustainable for a mass-market, low-margin giant like Costco. Networks need to remain agile and competitive in their fee structures, especially for high-volume merchants.
- For Consumers: The Need to Adapt and Evaluate Card Benefits. The split reminded consumers to regularly evaluate their credit card portfolios. What might have been the best card for specific spending categories (like the old Costco Amex for gas) might change due to market shifts or new offerings. Being flexible and open to new cards can lead to better rewards and benefits.
Frequently Asked Questions (FAQs)
Why did Costco only accept Amex for so long?
Costco exclusively accepted American Express for 16 years (1999-2016) due to a strategic, exclusive partnership. Initially, this deal likely offered Costco favorable terms on transaction processing fees and possibly other incentives that made the exclusivity worthwhile. American Express, in turn, gained unparalleled access to Costco’s high-spending, loyal membership base, significantly expanding its cardholder numbers and transaction volume. For a period, it was a mutually beneficial arrangement that provided a premium co-branded card to Costco members while securing a dominant position for Amex within the warehouse club’s ecosystem.
Did Amex lose a lot of customers after the Costco split?
Yes, American Express experienced a significant loss of cardholders and transaction volume following the termination of the Costco partnership. Costco was responsible for a substantial portion of Amex’s overall billed business, and millions of co-branded cardholders had to transition away from their Amex cards for Costco purchases. While Amex launched various initiatives to retain these customers by offering attractive alternatives and conversion programs, the split undeniably represented a major hit to their cardmember base and market share, leading to a period of adjustment for the company.
Can I use any Visa card at Costco now?
Absolutely. Since the switch in 2016, Costco warehouses in the United States exclusively accept Visa credit cards for credit card payments. This means you can use any Visa-branded credit card, regardless of the issuing bank, to make purchases at Costco checkout lanes. For other payment methods, Costco still accepts most debit cards (which typically run on major networks like Visa or Mastercard), cash, checks, and EBT cards.
What was the main benefit for Costco in switching to Visa/Citi?
The primary benefit for Costco in switching to Visa and Citigroup was a significant reduction in transaction processing costs, specifically lower interchange fees. As a retailer with razor-thin margins and massive sales volume, every fraction of a percentage point saved on “swipe fees” translates into millions of dollars annually. This cost saving allowed Costco to maintain its competitive pricing strategy for members and improve its own profitability. Additionally, the move to Visa offered broader payment acceptance for its members, enhancing convenience and ultimately, long-term member satisfaction.
Was the new Citi Visa card better than the old Amex TrueEarnings card?
While “better” can be subjective and depend on individual spending habits, for most members, the new Costco Anywhere Visa Card by Citi offered a more competitive rewards structure and greater overall utility. The Citi Visa often provides higher cash back percentages in key categories like gas (4% vs. 3% previously) and dining/travel (3% vs. 1% previously). Furthermore, as a Visa card, it boasts near-universal acceptance outside of Costco, unlike the Amex card which, while widely accepted, had a slightly smaller merchant network. This broader acceptance, combined with enhanced rewards, made the Citi Visa card a more valuable tool for everyday spending for many members.
Conclusion
The decision by Costco to end its long-standing, exclusive partnership with American Express was a watershed moment in the retail and credit card industries. It wasn’t a sudden whim but rather the culmination of years of financial negotiations and strategic positioning. At its heart, the split was driven by Costco’s unwavering commitment to its low-margin business model and its relentless pursuit of value for its members. The high interchange fees charged by American Express simply became unsustainable for a retailer that prides itself on offering the lowest possible prices.
By making the bold move to switch to Visa and partner with Citigroup, Costco not only secured more favorable processing fees, leading to significant cost savings, but also expanded payment flexibility for its vast membership. While the transition initially caused some disruption and frustration among loyal Amex users, the long-term benefits of broader acceptance and a more rewarding co-branded card ultimately reinforced Costco’s reputation for prioritizing its members. The great divide between Costco and Amex serves as a powerful reminder of the intricate financial dynamics at play in the modern retail landscape and how even the strongest partnerships can dissolve when core business philosophies diverge.
