It's against my principles to pay an interest fee. I pay the balance each month and I was a few days late sending it in because I was on vacation so I paid the fee but the next month I had a buck or two added because it had gone a couple of days into the next month. I called and told them to cancel (American Express). They took the charge off plus credited me the one from the month before and gave me double air miles for the rest of the year! Sometimes it pays to whine.
