Since we are talking about credit cards. An interesting thing happened to me a few weeks ago. I got a letter from my card company that said after analyzing my account they determined the net profitability was to low and they were raising my rate to 19.99% on anything charged after a specified date.
So watch out if you do not keep a max balance and only make minimum payments, the greedy SOB's will get you one way or another. The legislation passed to make credit cards better for all of us only made mine worse. Thank you congress for screwing me over by looking out for me!
