What's in Your Billfold?

realian001 asks: "I have been through many different types of wallets...(those long wallets, tri-fold, bi-fold, money-clips, etc, etc). I finally settled on a bi-fold, but I was just curious, how does the average Slashdot reader 'configure' their wallet? A type of wallet would be a good starting point, then having cash or not, and/or how many different types of credit cards, grocery discount cards, etc etc etc."
