Re: how many credit cards do you normally carry in your wall
1 debit, 2 credit and 2 store charges. I have one more store charge but it is so rarely used that if I go there they just look it up with my DL, no need to carry it.
eta: 1 credit is amex, 5% cash back for gas, grocery & pharmacy, 1% everywhere else, I use it for anything I can and pay in full each month, the other is for the random place that won't take amex
