Like a flock of geese, a wallet is filled with bills and should instinctually return home every spring after flying south to spend your money. Adopt a new pocket pet with today's Groupon: for $10, you get $20 worth of men's and women's wallets from Big Skinny.

A Guinness World Record holder, Big Skinny cradles stockpiles of cards, cash, and other important belongings inside sleek and durable wallets. Crafted from ultra-thin and resilient nylon microfiber and top-grain leathers, Big Skinny models weigh approximately one ounce and maintain a slender profile even when fully stocked with credit cards, business cards, and third-grade photos of ex-presidents. Designed to be one of the thinnest wallet lines in the world, each wallet is crafted with material 10 times slimmer than a traditional wallet and dries out within one hour of a full soak or machine wash. Customers can choose from 36 designs for men and women such as the multipocket bi-fold, which can pack away up to 25 plastic cards in pockets lined with rubber backing that prevents them from being lost when held upside down ($23.95). Containing four extra-wide pockets, the tri-fold wallet ($24.95) closes snugly around credit cards and Valentine snapshots, and red leather passport holders ($23.95+) keep couples sleek while jetting to romantic destinations or romantically breaking into the Kremlin. Big Skinny also bestows ultra-thin technology on money clips ($19.95), cell-phone wallets ($25.95), clutches ($29.95), checkbook covers ($13.95), and card holders ($7.95).
