Circuit City is not the same Circuit City folks are used to. The company went belly up and eventually the name, rights and customer list was bought by the same company that purchased CompUSA.Article, here.
The only reason I bring it up is because their return policy is not as generous as some may have been used to with the original brand, Circuit City.
More on the topic, my sister in-laws do the whole Black Friday thing every year. It's nearly a religion for them. There are great deals to be had but the stock is generally very low hence, the early morning stampede.
