Sam’s Club accepts all major credit cards, including Visa, Mastercard, American Express, and Discover. Unlike some warehouse stores, you are not limited to a single card network.
This makes Sam’s Club much more flexible at checkout compared to competitors like Costco.
As long as your card is issued from a U.S.-based account with a physical billing address, it will generally be accepted.
Note: PayPal is not accepted, and international credit cards are not supported.
Unlike Costco, which has an exclusive agreement with Visa, Sam’s Club does not limit itself to a single payment network. This allows them to accept all major credit cards and provide more flexibility to members.
For shoppers, this means you can use whichever card you already have without needing to apply for a new one.
This difference is important if you shop at both stores. At Costco, you must have a Visa card, while Sam’s Club gives you more freedom to choose.
Since Sam’s Club accepts all major credit cards, the best card to use is simply the one that gives you the highest rewards for your spending.
This could be a cashback card, travel rewards card, or even a store-branded card depending on your goals.
If you also shop at Costco, you may want to consider a Visa card so you can use it at both stores without restrictions.
If your card is declined, it’s usually due to one of these reasons:
In those cases, switching to another major credit card or debit card should resolve the issue.
Sam’s Club accepts all major credit cards, including Visa, Mastercard, American Express, and Discover, both in-store and online.
This makes it one of the most flexible warehouse clubs when it comes to payment options, especially compared to Costco’s Visa-only policy.

A FICO® Score is a proprietary credit score created by the Fair Isaac Corporation (FICO). About 90% of top U.S. lenders use it to make lending decisions.
FICO® Score Ranges:
FICO categorizes scores as Poor, Fair, Good, Very Good, and Exceptional.
A credit score is a three-digit number (300–850) predicting your creditworthiness. Lenders use it to evaluate risk and determine rates and terms for credit.
Why it matters: A higher score can help you qualify for loans and lower interest rates. A lower score can lead to higher borrowing costs or application denials.
Note: Credit scores reflect your creditworthiness but do not guarantee approval for any credit product.
