If you've ever wondered whether there's any way to get a credit card company to waive its annual fee, there's no harm in asking. Call your card company and explain that you'd like it to waive the fee and that if it won't, there are plenty of cards with no fee that you can switch to. With some companies, it'll work; with others, it won't.

Some issuers have imposed annual fees on cardholders who pay off their bills in full each month, essentially penalizing them for not generating enough income from interest charges for the issuer. Sheesh. If your card company is that obnoxious, tell it you'll take your business elsewhere unless it waives the fee -- and then leave if the issuer refuses!
