shopgoodwill.com has been around for ages. I've had problems with them in the past. First they decided they didn't like my user name and blocked me. It wasn't anything offensive or bad but the person running the website is over zealous at deleting anything even remotely related to something that might be offensive. I have recieved items that were broken in shipping due to poor packing. You really, really need to know the actual value of the items you're bidding on or you can get stuck with expensive junk.
