REI Outlet has Additional 20% Off for Members after applying coupon REIANNV. Here is a screenshot for your reference. Note that REI Membership is $20 and is valid for lifetime, which means if you spend more than $100, it is a good idea to sign up for membership just for the discount and can be used for life. Shipping is free for orders over $100.
