Recreational Equipment Inc.
Kent, Washington based consumers' cooperative that sells outdoor recreation gear and sporting goods. You can join for a nominal one-time fee (I think it is still $20), which allows you to get a dividend - usually about 10% of your purchases - which can be applied toward furhter purchases.
Great source for gear for camping, backpacking, biking, kayaking, climbing, and all-around outdoorsy gear and clothes.
