You Can Even Return Your Membership
Shopping at a warehouse club isn’t for everyone. If, after joining Costco, you decide you aren’t getting the best value on the products you buy or you simply don’t shop enough to justify paying the annual fee, you can cancel your membership anytime and get your money back.
All you have to do is visit your local Costco, go to the membership desk and request to close your account. As part of Costco’s “Risk-Free 100% Satisfaction Guarantee,” your membership will be cancelled and you’ll receive a full (not prorated) refund of the annual fee on the spot — no questions asked and no cancellation fee.
