I know someone that used Qbid (or Beezid, i don't remember) for a little bit. He had some success and actually got something real. It was a semi-decent quality product. Black and Decker high speed buffer/polisher for something like a car. He got a few other things as well. He tried to go for a TV but, as you can imagine, it was a little more difficult. This guy is far from a rocket scientist, so apparently it did not take a lot of sense to use it. However, I wouldn't bother. For what I want, too much of a pain in case it is broken when I get it.
Overall, I rate it a 5. Awesome if you could get what you want for very cheap, but has the potential to be a waste of time when you could just go to the store or Amazon.com and buy what you wanted way faster.
my two cents.
