I've found stuff in wal mart, and also in old navy. I bought a couple of synthetic runners style tops
there a few years ago for something like 6 or 8 bucks each. they're holding up fine. If you look in my
pics I often wear the green one, which is in better shape than the grey one, the grey one having survived several truly horrible bushwhacks and a stupid fall on a scree slope that has left it looking somewhat "damaged" but still quite serviceable.. (I was more damaged than the shirt)

I scored a *merino wool* long sleeve top for *15 dollars* at costco a few years back too. it's just as nice as my MEC ones, but well, a lot cheaper. My only regret is I didn't buy two.

Thrift stores are also an execllent source for things like cashemere and merino sweaters, fleece, synthetic pants, etc.
