Discover card, 0% apr for 15 months?

That is soooooooooo funny, because only two hours ago, my bf DAVE was asking about the Discover card! Anyhow, As long as you pay the balance IN FULL by the end of 15 months, you get no interest, penalty, nothing. But I'm gonna tell you right now, if you pay only the minimum balance, odds are you will not pay if off, divide the whole amount you spend by 15, that's how much you need to average each month to ensure you won't have a balance. But if you do, you'll only get interest each month on that unpaid amount, whatever the going rate is, so if you paid it under maybe five hundred bucks, shouldn't be too bad.
