General information about the best credit cards to use at Costco in Canada:

Costco only accepts Mastercard credit cards at their warehouses in Canada. In the USA, they only accept Visa credit cards, and Mastercards are not accepted.

Shopping online at Costco.ca is not the same as shopping in the store. For online shopping, Costco accepts both Mastercard and Visa credit cards. They longer accept Amex – even online.

The Capital One Platinum Mastercard exclusively for Costco members gives you decent rewards for a no fee credit card and doubles as your Costco membership card reducing the clutter in your wallet.

The downside is that you’ll only earn 1% on your purchases actually made at Costco with the card. Other fee-based and no fee credit cards can earn you between 1-2% cash back on all your purchases at Costco and anywhere else. With the Costco Mastercard, you’re also forced to redeem your cash rewards in-store, whereas other cards let you get your cash as a statement credit or even a cheque or direct deposit.

You can use your Costco credit card anywhere Mastercard is accepted, worldwide. You earn the same rewards (or more) as you would at Costco itself.

Many credit cards offer more rewards that the Costco card on grocery store purchases. A large number of Canadians consider Costco to be a grocery store, but it’s not categorized as a grocery store by the Mastercard network. Therefore purchases made at Costco are not eligible for grocery bonuses. In fact, Costco does not qualify for any credit card bonus category that Costco qualifies for at all.

Costco does not take Visa in their Canadian warehouse stores. However, they do take Visa online (Costco.ca). All of their stores in the United States also accept Visa. One way to use Visa at Costco is by buying Costco Cash Cards online with your Visa credit card. You can get points and rewards ‒ and then use your cash cards in the actual store to make your purchases.

Costco also accepts debit cards at all their warehouses, as well as Mastercard credit cards.
