Yup. The cashier will ask for a Costco ID but then you can just swipe whatever credit card you want. Officially, it's Costco's policy to only allow a credit card that matches the member's name, but in reality cashiers don't check/care.

You can also get into and pay at a Costco if you have a Costco Cash card. Those can be bought online by anyone with a membership and used whether you have a membership or not. At checkout, you have to pay for part of your purchase with the Cash Card (I think $10), but the rest can be paid with a credit card, in my experience.
just got $20 off $20 for an amazon purchase today on 1 of 3 cards
