I have had the card for 6 months or so. Ran up quite a large bill as we always use and have used the AMEX green card for the last 30 years. I guess I misunderstood that there was no late fee so when I mailed a payment of $5000 it was received a little late so they showed me as late and subsequently put 30% interest on my account. I spoke to them this A.M. and they said that they don't charge a late fee, but do put higher interest on the account when I am "late". I have never been charged any kind of fee or interest on my Am Ex card and don't know if this is false adv or not. I am paying ff the card and cancelling it. I will keep my green and my optima as the 30% interest is excessive. I was initially told there was no interest at all. I will be contacting some one in authority at AM EX, but for now I am paying the balance and probably cancelling the card. I guess it's buyer beware abd read the fine print.
