Just to add to this good advice:
We pay with gift cards that we purchase at our local grocery store chain (Giant Eagle). We get 2% back in Mickey bucks (Disney visa) and get 10 cents off per $50 spent on per gallon of gas. It's not a ton of savings, but every little bit helps and it does add up. Lots of people do the Target red card deal as well for 5% off gift cards. You just need to make sure you go online and pay each month prior to the withdrawal.
