NEVER pay anything with a credit card if you can't pay it back right now. Credit cards, whilst not having interests right away, which is good, are, apart from suspicious arrangements, the highest interest sort of credit there is. Why do you think they go through the trouble of lending you money for free? Because when people don't pay, it's their best source of money interest profit. Or one of the best.
It's WAY too high. If you're gonna borrow money, don't do it this way.
