For some people, a wallet is a constant companion. You carry it with you every time you leave the house. So, choose wisely. Some folks want the thinnest wallet they can get by with, as long as there’s room to stash a bit of cash and a few cards. Others treat a wallet like a miniature briefcase, stuffing it with receipts, notes, pocket change, and dry-cleaning ticket stubs. Think about what you want to carry, and whether you need a wallet that goes in a back pocket or a front pocket. Then think whether you need these other features before you buy.
