If you have an REI local to you and you're a member of the coop, check out the garage sale section. Thats where they sell customer returns. Each item generally has a justification as to why its returned. You'll see things like "item was too small," "customer preferred different model," etc. I have had pretty good luck with things such as outer layer, some electronics, and others that I otherwise wouldn't pay retail for.
I picked up a 120w goal zero yeti 200X for $125 the other day because the previous owner "wanted the larger model" in the garage sale section. It lives in my car for additional means of power when i go out for the extended match or event.
Garage sale section plus the $100 gift card could save you a lot on something you stumble upon.
