Citibank tried that little trick on me last month. One phone call got my APR back down to where it was. I have had an account with them for close to 15 years now and this is the first time I can remember my interest rate taking a huge jump. I guess they figure that most Americans don't even bother to read their statement when it comes in the mail. They just mail in the minimum payment and stretch their debt out for another month.

I was actually surprised that they lowered it with no argument. I guess sometimes all you gotta do is ask.
