How much is the membership?

if you apply for the citi visa card..it includes your membership you get 4% cash back from costco gas..lower % on other purchases..

60 or 120

$60 for Gold member (was $50) and $110 for executive. If you live close to a Costco, shop there regularly, and get your gas then you can the membership will pay for itself

Varies...ours is $110 I believe but you get 10% back each year...usually pays foritself

That is $50 per year.

I paid $50 for my yearly basic membership- when I ran a few numbers, the membership more than paid for itself with theor always "beat the competition" gas prices for the year. I bought the membership just for gas privileges because Iblive really close to a Costco and now I only get my gas there, but of course have used the membership to buy groceries as well.
