Remember my post previously on rolling $$ over credit cards. The problem with that was that we are usually not able to draw cash from one credit card and use it to pay for the other credit card.
However, it is actually possible to so called 'change' your debt from one company to another. And in the process reduce your monthly 2% interest to a one time admin fee ( from 1.5-6.5%) for 6-24months. I.e. you pay less for interest by shifting your debt around, then letting one particular credit card company charge you interest.
Here are the rates.
