No....i got a TV for a steal at one of those maybe 10ish years ago. Basically you ordered it online, and they gave you a time to come to the warehouse to pick it up.

It was totally legit, through the manufacture (was Sharp) clearing out previous years stock. The exact tv was still on the shelves at the time for 3x what i paid.

I think the truth of the matter is with the internet the way it is, its easier and more economical for places to just sell excess stock to a wholesaler in one shot.
