Costco only takes cash and debit, not credit.

Costco accepts all VISA credit cards and offers a Costco Citi VISA card

VISA only charges 0.4% fees to Costco

Huh? That’s not true at all. I use my credit card at Costco all the time.

I’m just assuming they aren’t that familiar with Costco and are misunderstanding that they only accept VISA cards as they don’t accept credit cards
