None. The only credit card I have is a business travel card from my company. I buy what I can, when I can. Now if you were to ask what % of my monthly income goes to Ball Pythons and their stuff...that would be a very different strory.

Suffice it to say, I have actually had conversations in my head about how I really need one more RBI rack, and eating 4 for a dollar mac&cheese for two weeks really isn't all that bad.
