Sam's Club Credit Cards Don't Work at Walmart
No, you cannot use a Sam's Club credit card at Walmart. Sam's Club and Walmart are separate retailers with their own payment systems, even though Walmart owns Sam's Club. A Sam's Club Mastercard or Sam's Club store card will be declined at Walmart checkout.
The two companies operate independently for membership and payment. Your Sam's Club membership card and Sam's Club credit card are tied to the Sam's Club ecosystem only. Walmart has its own credit card products and does not accept Sam's Club cards as payment.
If you shop at both retailers, you will need separate payment methods for each. Many people hold both a Sam's Club card and a Walmart credit card to earn rewards at each store.
Key Takeaways
- Sam's Club credit cards will not work at Walmart registers, even though Walmart owns Sam's Club.
- Sam's Club and Walmart maintain separate payment systems and do not cross-honor each other's cards.
- You can use a regular Mastercard or Visa at both retailers, but store-branded cards only work at their own chain.
- Walmart offers its own credit card and rewards program separate from Sam's Club benefits.
- A regular debit card, Mastercard, or Visa will work at both Sam's Club and Walmart without issue.
What Payment Methods Work at Both Retailers
If you want one card that functions at both Sam's Club and Walmart, use a standard Visa or Mastercard that is not store-branded. Any major credit card, debit card, or prepaid card issued by a bank will work at both locations. This includes cards from Chase, Bank of America, Capital One, American Express, and other financial institutions.
You can also pay with cash, checks, or digital wallets like Apple Pay and Google Pay at both retailers. The restriction only applies to store-branded cards—the ones that carry the Sam's Club or Walmart name and logo.
Sam's Club Credit Card Options and Rewards
Sam's Club offers two credit card products: the Sam's Club Mastercard and the Sam's Club store card. The Mastercard can be used anywhere Mastercard is accepted, but the store card works only at Sam's Club locations. Both cards earn rewards on purchases, but those rewards are designed for Sam's Club members.
The Sam's Club Mastercard earns cash back on Sam's Club purchases and also on gas, travel, and dining outside the club. The store card earns rewards only at Sam's Club. If you use the Mastercard at Walmart, you will earn rewards at the standard Mastercard rate, not at the Sam's Club rate.
Neither card gives you access to Walmart's rewards program or Walmart+ membership benefits.
Walmart's Credit Card and Rewards Program
Walmart has its own Walmart credit card and a Walmart+ membership program with separate rewards. The Walmart card earns cash back on Walmart and Walmart.com purchases, plus gas and travel rewards. This card does not work at Sam's Club.
If you want to earn rewards at Walmart, you need the Walmart card or a Walmart+ membership. Sam's Club membership and rewards do not transfer to Walmart, and vice versa. The two retailers keep their loyalty programs completely separate.
Why Sam's Club and Walmart Don't Share Payment Systems
Even though Walmart owns Sam's Club, the two operate as distinct brands with different customer bases and business models. Sam's Club is a membership warehouse, while Walmart is a traditional retail store. Their separate payment systems reflect their different pricing structures, membership requirements, and reward programs.
Keeping the systems separate also protects each retailer's data and allows them to track customer spending patterns independently. This separation lets each company tailor rewards and promotions to its own shoppers.
What to Do If Your Sam's Club Card Is Declined at Walmart
If you accidentally tried to use a Sam's Club card at Walmart and it was declined, this is expected behavior. The card is straightforward not authorized for use outside Sam's Club locations. You will need to use a different payment method.
If you have a Sam's Club Mastercard (not the store card), check whether it is a Mastercard-branded card or a store card. The Mastercard version should work at Walmart because it is a standard Mastercard. If it still does not work, contact Sam's Club customer service to confirm the card type and check for any account holds or fraud blocks.
Frequently Asked Questions
Can I use my Sam's Club membership card at Walmart?
No. Your Sam's Club membership card is only for entry to Sam's Club warehouses. It is not a payment card and will not work at Walmart registers. You need a separate payment method like a credit card or debit card to pay at either retailer.
Will a Walmart credit card work at Sam's Club?
No. The Walmart credit card is accepted only at Walmart and Walmart.com. It will not work at Sam's Club. You would need a Sam's Club card or another payment method to shop at Sam's Club.
Can I use a Sam's Club Mastercard at Walmart?
Yes, if your card is a Sam's Club Mastercard (not the store card). A Mastercard-branded card works anywhere Mastercard is accepted, including Walmart. However, you will not earn Sam's Club rewards on the Walmart purchase—you will earn standard Mastercard rewards instead.
What if I have both a Sam's Club card and a Walmart card?
You can use each card at its respective retailer to earn the best rewards. Use your Sam's Club card at Sam's Club and your Walmart card at Walmart. For other retailers, use a standard Visa or Mastercard from your bank.
Do I need both a Sam's Club membership and a Walmart+ membership?
No. They are separate programs. You can have one, both, or neither depending on where you shop and what benefits matter to you. Sam's Club membership gives you warehouse access and rewards. Walmart+ gives you delivery and shopping benefits at Walmart stores and online.
