How much does it cost for a Costco card?
It depends on what kind of card you would like to get, here is more information about their membership: http://shop.costco.com/membership/join-costco.
It was $30, but might have gone up with the economy the way it is.
I believe it is $50 for a 2 person card that lasts 12 months, and it is $100 for an executive card that lasts 14 months.
theres 3 different types of memberships but the one that is for basics(just for groceries) would be $50 a year.
