In ShortThis sporting goods chain offers new and used equipment, name and generic brands and men's and women's merchandise. The selection of used equipment is staggering: boxes of golf tees, dozens of snowboards, racks of football padding, shelves of baseballs, a wall of hockey sticks, and a decent selection of treadmills, stationary bikes and home gyms. New items are available, but it's the resale offerings that reign.
