If you're planning to wander into the outdoors, REI will have just about anything you could possibly need. REI sells top-notch clothing and equipment for everything from camping, backpacking and canoeing to biking, skiing and rock climbing. (You can even try rock climbing in the store or sign up for one of many other outdoor group activities posted in the lobby.) These goods aren't cheap, but REI's retail prices are reasonable, particularly if you become a member. But what puts this store over the top is its sales: When they say sale, they mean it. We're talking 50 percent or more off on goods throughout the store. You don't have to become a member to shop here, but if you do, the $15 fee you spend to join will quickly turn into big savings.
