If you have patience like me, REI garage sales are incredible. I always camp out, part of the fun, but also beats getting up at 5am and still not being first in line. So I just sleep out with some buddies, or even solo, with a few brews and some whiksey. I find 80% of the gear to be in such amazing condition you wonder how REI stays afloat selling em at such ridiculous discounts. Some of my best finds (all in great-like new condition unless otherwise noted)

REI Shuksan rainshell, normally $300, attained for $100.
Osprey Kestrel 38 ($149) for $50 (was missing center lift strap is all)
Asolo Fugitive GTX ($240) for $40 cuz of an unnoticable tear in the liner. Feet stayed dry though.
Gently used Merrell Chamelon ($110) for FIVE bucks.
Half off a pair of Darn Toughs that never even left the store but were found on the sales floor with no tag.

And the best deal of all? Sea to Summit 2L dry sack ($12.95) for THREE CENTS hahaha.
