Using Your Sam's Club Credit Card at Walmart and Other Stores

Sam's Club Credit Card at Walmart: What Works and What Doesn't

No, you cannot use a Sam's Club Mastercard at Walmart. Sam's Club and Walmart are separate companies, and Sam's Club issues its own branded credit card that works only where Mastercard is accepted — not at Walmart stores themselves. If you want to use a credit card at Walmart, you'll need a Walmart credit card, a regular Mastercard or Visa, or another card that Walmart accepts.

The confusion happens because both companies are owned by the same parent corporation, Walmart Inc., but they operate as distinct retailers with their own payment systems. Sam's Club membership and its credit card are tied to the Sam's Club warehouse experience, not the Walmart store experience.

Key Takeaways

• Sam's Club Mastercard cannot be used at Walmart stores, even though both are Walmart Inc. subsidiaries.
• You can use a Sam's Club Mastercard anywhere Mastercard is accepted outside of Walmart — gas stations, restaurants, online retailers, and other merchants.
• Walmart has its own credit card (Walmart Mastercard) that earns rewards at Walmart and Sam's Club, plus other retailers.
• A regular Mastercard or Visa from any bank works at both Walmart and Sam's Club without restriction.

Where Your Sam's Club Mastercard Actually Works

Your Sam's Club Mastercard is a standard Mastercard, which means it works anywhere Mastercard is accepted globally. That includes gas stations, grocery stores, restaurants, online shopping sites, and thousands of other merchants. The card is not restricted to Sam's Club locations — it's only restricted from being used at Walmart stores specifically.

The card earns rewards when you use it, but the rewards structure depends on which version of the Sam's Club Mastercard you hold. Some versions offer cash back on all purchases, while others offer higher cash back rates at Sam's Club and gas stations. Check your cardholder agreement or log into your account to see your specific rewards rate.

Why Sam's Club and Walmart Don't Share Payment Cards

Even though Walmart Inc. owns both companies, they maintain separate payment ecosystems. Sam's Club operates as a membership warehouse club with its own checkout system, pricing, and product selection. Walmart operates as a traditional retail store. Each company issues its own branded credit card to encourage loyalty to that specific brand.

This separation is intentional. Walmart wants customers who shop at Walmart to use the Walmart Mastercard and earn Walmart rewards. Sam's Club wants members who shop at Sam's Club to use the Sam's Club Mastercard and earn Sam's Club rewards. Allowing one card to work at both locations would blur that distinction and reduce the incentive to use the branded card at each store.

What Credit Cards Walmart Actually Accepts

Walmart accepts the Walmart Mastercard (its own branded card), plus any Mastercard or Visa from any bank, American Express, Discover, and digital payment apps like Apple Pay and Google Pay. You can also pay with debit cards, prepaid cards, and cash.

If you want to earn rewards specifically at Walmart, the Walmart Mastercard is your option. It earns cash back on Walmart and Sam's Club purchases, plus gas station purchases. If you don't have a Walmart card, any Mastercard or Visa will work fine — you just won't earn Walmart-specific rewards.

If You Shop at Both Walmart and Sam's Club

If you're a Sam's Club member and also shop at Walmart, you have a few options. You can carry both the Sam's Club Mastercard and the Walmart Mastercard — use each at its respective store to earn rewards at both places. You can use a regular Mastercard or Visa at both locations without earning branded rewards. Or you can use whichever card you prefer at each location, knowing that only the branded cards will earn rewards.

The Walmart Mastercard actually works at both Walmart and Sam's Club, so if you want one card that earns rewards at both locations, that's your best choice. The Sam's Club Mastercard only earns rewards at Sam's Club, not at Walmart.

Using Your Sam's Club Card Online and Internationally

Your Sam's Club Mastercard works for online shopping at any retailer that accepts Mastercard, not just Sam's Club's website. You can use it on Amazon, Target, airline websites, subscription services, and anywhere else Mastercard is accepted online. International travel also works — Mastercard is accepted in most countries worldwide, though you may pay a foreign transaction fee depending on your card's terms.

Check your cardholder agreement for foreign transaction fees before traveling. Some Sam's Club Mastercards charge a percentage fee for purchases made outside the United States, while others do not. You can also call the customer service number on the back of your card to ask about fees before you travel.

Frequently Asked Questions

Can I use my Sam's Club Mastercard at Walmart gas stations?

No. Walmart gas stations are part of Walmart's payment system, not Sam's Club's. You would need a Walmart Mastercard or another card Walmart accepts. However, your Sam's Club Mastercard does work at other gas stations that accept Mastercard, and some versions earn higher cash back at gas pumps.

What if I try to use my Sam's Club card at Walmart?

The transaction will be declined. Walmart's payment system is programmed to reject Sam's Club Mastercards at checkout. You'll need to use a different card — a Walmart Mastercard, a regular Mastercard or Visa, or another payment method Walmart accepts.

Does the Walmart Mastercard work at Sam's Club?

Yes. The Walmart Mastercard is accepted at Sam's Club locations and earns rewards there. If you want one card that works and earns rewards at both stores, the Walmart Mastercard is the better choice than the Sam's Club Mastercard.

Can I use my Sam's Club card for online purchases at Walmart.com?

No. Walmart.com is part of Walmart's payment system and will not accept a Sam's Club Mastercard. You would need a Walmart Mastercard or another card Walmart accepts online.
