They do not accept American Express, Diners Club, or Discover but do accept Visa and MasterCard.

I'm pretty sure they do.

No American Express only Visa.

Can you join on line

I'm pretty sure only Visa card but I'm in Arizona

Yes

Yes they do. Costco made a big splash recently with the news it had finally started accepting Visa credit cards. For consumers — including me — this is a big win. Since 1999, the retail giant had accepted only American Express credit cards, excluding credit cards from other payment networks, including Visa, Discover and MasterCard.Jul 5, 2016
