Where you can use your Walmart credit card will depend on which Walmart credit card you have:
The Walmart Mastercard (issued by Capital One) can be used anywhere that Mastercard is accepted, which is pretty much everywhere credit cards are accepted, so this card is really just like any other Mastercard credit card. Use it at Walmart or Sam’s Club, but then use it anywhere else that accepts Mastercard.
In fact, you’ll even get extra cash back rewards when you use your Walmart Mastercard outside of Walmart, including 2% cash back on restaurant purchases, 2% back on travel purchases, and 1% back everywhere else Mastercard is accepted. (Of course you’ll also get 5% back at Walmart.com and 2% back in Walmart stores and Walmart/Murphy USA fuel stations.)
Walmart Rewards Card (Store-Only Credit Card)
If your Walmart credit card is NOT a Mastercard (does not have the Mastercard logo on it), then it is not accepted everywhere. Instead, you can only use it for Walmart purchases, which includes Walmart stores, Walmart.com, the Walmart App, and at Walmart and Murphy USA Gas Stations. This card is also accepted inside Sam’s Club stores and for Sam’s Club gas, but not on SamsClub.com.
