-How's your credit score? How well this works totally depends on YOU, but I had a lot of luck moving money around... got one new card with a 0% balance transfer offer. Moved enough onto that card, that we paid it off with 0% interest. Then Old Card #1 offered a 0% transfer... so moved money from Old Card #2 to #1. Etc. It became a shell game of knowing which card had the best offer and how much we could realistically pay within the time limit.
We were masters at that while we had credit card debt, but I think the banks have made this a lot more difficult to do lately. Lots of one-time balance transfer fees of 1% of the balance, for instance.
