If you can charge what you can pay in a month or two, awesome!
If you need to charge something that you can't pay right away, look for places with "same as cash" deals, where if you pay it within the period allowed, you pay no interest.
If you can't find any "same as cash" deals and have to use a high interest card, focus on paying that off right away. It is the worst kind of debt anyone can possibly have.
I feel fortunate that my card charges me 6% and heck if they get to see much interest money out of me.
