Mrd - I don't know if any other stores do this, but I know Lowe's gives really good deals on their dented and scratched products. My folks got a full-size standing freezer for $100. The only thing wrong with it was a scratch on the side. I'd ask around at the local stores to see if they have a dent and scratch department. You can get amazing deals.
Rattus is right - you can get great deals on freecycle.
