Be care about "liquidations" like Circuit City

Retail chains typically outsource their liquidations to third parties who bid for and buy up inventory at one or more B/M (brick & mortar) locations. They then staff the location with their own people, mark-up the prices while also showing a mark-downed discount to leave you with the impression that the item is below retail. They'll even stock the location with merchandise they couldn't sell at the previous liquidation they ran. So, unless you wait to until close to the last day of the liquidation before they close the doors to buy something that's in low demand and hard to move (e.g. a sofa), it's probably better to visit eBay for the best deals on what you really want.

Circuit City is going out of business -- FAQ

I buy my electronics from Amazon, Crutchfield, or J&R Music. Good service, and no hassles to buy a useless warranty, or ridiculously overpriced cables.

My experience with CC has been pretty limited and I don't think I've bought anything from them that I can remember. Best Buy can be good or bad for me.... Sometimes their sales staff is incredibly annoying yet other times good.
