Wrong It takes American Express too.

  They used to be AmEx only. They're now Visa only.

AmEx not listed anywhere. Maybe yours does something different, or it's an AmEx branded debit card, or you're not in the US and they do something different abroad, but no Costco I've been to since the switch has accepted any credit card that isn't a Visa.
