I use a credit card for everything. I don't carry a balance. It's paid off every month. I only use credit cards that give back something.
I used to have a GM card while I worked at Bose. We got the supplier discount plus any incentives plus the GM points I used to get my vehicles at a pretty damn good deal.
Now I use an Alaska Airlines card for everything except for gas. Gas I use a US Airways card, with those two cards I can transfer miles to just about any airline.
I'm flying to the Dominican Republic in January and used my miles only cost me $100.
If your going to use a card get some sort of benefit that you know you'll use.
