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 $12, you get $25 worth of 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 1 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. With the multi-pocket bi-fold, wallet holders 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). The tri-fold wallet contains four extra-wide credit-card pockets and closes to a thickness of 5 millimeters ($24.95). Big Skinny also bestows ultra-thin technology on passport holders ($23.95+), money clips ($19.95), cellphone wallets ($25.95), clutches ($29.95), checkbook covers ($13.95), and card holders ($7.95).
