You can’t use your Mastercard credit card at Costco, because Costco has a contract with Visa. You can, however, use your Mastercard credit card for purchases made at Costco.com and through the Costco app. For their warehouse locations Costco only accepts cards on the Visa network.
So, if you only have a Mastercard and want to shop at Costco, you have a couple choices. For starters, you can still pay for Costco items with cash or a check. But if you don’t really want to carry all that cash, take the time to write out a check or miss out on a lot of rewards, your best bet is to simply get a Visa credit card.
