Short answer, I just walked in and bought it. Only went there to pick up a $20 ordered item and walked away with a $550 TV.
Bear in mind I also went to another BB to pick up another ordered item and didn't see these TVs anywhere. When I asked about them I was told they were in the back and would not be put out until Black Friday. Sooo, it seems store specific. The first BB had tons of them right when you walked in... so I bought one. This was clearly an impulse buy. Good luck with your purchase.
