I guess it'll be even more official when the credit card people get around to mailing me a statement.
I'm tempted to cut the card into little bits, and maybe I will, but I wouldn't have been able to pay it off if I didn't have the discipline to not use the card already.
My next priority, of course, is the next-highest interest rate card. Curiously, and somewhat fortuitously, the last card is a Discover. And nobody takes Discover.
