ReturnBuy has Olympus C-720 (sells for $599 at Best Buy) for $309. It appears to be an open box item, but they claim it's fully functional, and all the accessories are included. Not too bad of a price IMHO, I just ordered one. Just go to returnbuy.com and search for C-720. I think they use session IDs, so I'm not going to post a direct link. They also have open box D520 for $139 and D550 for $199.
PS: I got my C720 from them a few days ago, it was like new.
