I have no idea how people can get by using a billfold or French accordion type wallet. Now granted, maybe I just sign up for way too many Rewards cards but by the time you put in a BI Card, Optimum Card, Sally's card, picture ID there's hardly any room for CCs or anything. Maybe I could just one of those ID card case things, but I have enough of a time trying to locate my wallet, without having to search for another Skinny/SLG.
Certainly, smaller wallets are usually cheaper, but I just couldn't do it.
