I think that half my gear and clothes came from REI Garage Sales. I've gotten some awesome things for cheap cheap there over the years. Too many to list them all. Right now I'm wearing an Isis fleece jacket that I got for $4.

We have a tiny REI here in town. Walking distance from my apt even. They used to have large garage sales every few months. Now they have a small inside garage sale every Saturday. I try to stop by and check it out. I have $40 dividend plus a $20 gift card to spend sometime. I seldom shop retail at REI.
