Looking for a place besides Wal-Mart to get affordable stuff.

I am currently in the market to get some winter underwear aka long johns and maybe a few jogging outfits. i refuse to go against my ideals and shop at Wal-Mart. Does anyone know of anywhere i can purchase everyday stuff for low prices, preferably made in the u.s.a? I can smell where this thread is going and its a shame if no such place exists other than china or india along with all our manufacturing jobs.
