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

Your Sam's Club Mastercard works at Walmart, but only as a regular Mastercard — you won't earn Sam's Club rewards on the purchase. The card itself is a Mastercard, which means any merchant that accepts Mastercard will take it. Walmart accepts Mastercard everywhere: in-store, online, and at self-checkout. The limitation is not whether the card will be accepted, but whether you'll earn the bonus rewards that make the card worth carrying.

Sam's Club issues two versions of its credit card: the Sam's Club Mastercard and the Sam's Club Business Mastercard. Both are Mastercards, so both will work at Walmart. The difference is in the rewards structure and the membership tier you need to hold them. Neither card earns bonus rewards outside Sam's Club, so using it at Walmart gives you the same cash back you'd earn with any other Mastercard — typically 1% or less, depending on the card's base rate.

Key Takeaways

  • Sam's Club Mastercard is accepted at Walmart because it is a Mastercard, but you earn no bonus rewards on the purchase.
  • The card earns higher rewards inside Sam's Club (typically 2% to 5% depending on category) than it does at other retailers.
  • If you shop at both Sam's Club and Walmart regularly, using the Sam's Club card at Walmart is convenient but not rewarding.
  • You must hold an active Sam's Club membership to use the Sam's Club credit card, even if you're only using it outside the club.

Where the Sam's Club Card Earns Rewards

The Sam's Club Mastercard earns its highest rewards inside Sam's Club locations. The exact rate depends on which version of the card you hold and what you're buying. Fuel purchases at Sam's Club typically earn 5% cash back, groceries and other in-club purchases earn 2%, and everything else earns 1%. These rates are significantly higher than what you'd earn using the card at Walmart or other retailers.

Outside Sam's Club, the card earns a flat rate on all purchases — usually 1% cash back, though this can vary. That 1% applies whether you're at Walmart, a gas station, a restaurant, or anywhere else that accepts Mastercard. The card's real value comes from the Sam's Club rewards, not from using it as a general-purpose card elsewhere.

Membership Requirements and Card Activation

You cannot open a Sam's Club credit card without an active Sam's Club membership. The membership itself costs money — either a basic membership or a Plus membership, depending on which tier you choose. You must maintain that membership to keep the credit card active. If your membership lapses, your card may be deactivated or closed.

This is different from many other retail credit cards, which don't require you to maintain a store membership to use the card. With Sam's Club, the membership is a separate cost on top of the card's annual fee (if any). Check the current membership pricing on Sam's Club's website, as these costs change and vary by location.

When Using the Card at Walmart Makes Sense

Using your Sam's Club card at Walmart is practical if you're already carrying it and don't have another card in your wallet. Since it's a Mastercard, it will be accepted everywhere Walmart accepts Mastercard. The convenience of one fewer card to carry is real, even if you're not earning bonus rewards.

However, if you're choosing which card to use specifically for Walmart purchases, the Sam's Club card is unlikely to be your best option. A card designed for grocery or general retail rewards will earn more cash back at Walmart than the Sam's Club card's flat 1% rate. The Sam's Club card's strength is earning 2% to 5% inside the club, not competing with other cards at other retailers.

Online Shopping and Digital Wallet Use

The Sam's Club Mastercard works online at Walmart.com the same way it works in physical stores — as a regular Mastercard with no bonus rewards. You can also add the card to digital wallets like Apple Pay, Google Pay, or Samsung Pay and use it for contactless payments at Walmart. The rewards structure doesn't change; you still earn only the base rate outside Sam's Club.

If you're shopping online at Sam's Club's website, the card will work there and earn the club's rewards rates. The key difference is the merchant: Sam's Club's website recognizes the card as a Sam's Club card and applies the higher rewards, while Walmart.com sees it as a standard Mastercard.

Alternative Cards for Walmart Shopping

If you shop at Walmart frequently and want to maximize rewards, a card designed specifically for Walmart or general retail may serve you better. The Walmart credit card (if you're approved) typically offers higher rewards rates at Walmart than the Sam's Club card does. Cards that earn 2% to 3% cash back on groceries or general purchases will also outperform the Sam's Club card's 1% rate at Walmart.

The Sam's Club card remains the better choice if you shop at Sam's Club regularly and want one card that works everywhere. But if Walmart is your primary retailer and you don't have a Sam's Club membership, a different card will likely earn you more rewards per dollar spent.

Frequently Asked Questions

Will my Sam's Club card be declined at Walmart?

No. Since it's a Mastercard, Walmart will accept it at checkout, online, and at self-service kiosks. The card will not be declined for being a Sam's Club card — Walmart doesn't restrict which Mastercards it accepts.

Do I earn Sam's Club rewards when I use the card at Walmart?

No. Rewards are tied to the merchant, not the card. When you use the card at Walmart, Walmart's payment system processes it as a standard Mastercard, and you earn only the base cash back rate (typically 1%), not the higher Sam's Club rewards rates.

Can I use the card if my Sam's Club membership expires?

Your card may stop working if your membership lapses. Sam's Club ties the credit card to active membership status. If your membership expires, contact Sam's Club to confirm whether the card remains active or needs to be reactivated once you renew.

Is there an annual fee on the Sam's Club credit card?

The Sam's Club credit card itself typically has no annual fee, but you must pay for your Sam's Club membership separately. That membership fee is the primary cost of holding the card. Check Sam's Club's current pricing for membership tiers, as these costs vary.

What if I want to earn more rewards at Walmart?

Look for a card that earns 2% or higher cash back on groceries or general purchases. Cards designed for grocery shopping or everyday spending will typically earn more at Walmart than the Sam's Club card's 1% base rate, unless you're buying items in categories where the Sam's Club card earns bonus rewards.
