I had an older Toshiba notebook for years. It was pretty heavy to carry around, but also built like a tank. Finally it failed and time to buy a new one.
I went to Best Buy looking for the best bang for the buck to support my 3D graphics work. I found a cheaper model, "Matrix" it was called, made for Best Buy. 2.4G, 30GHD, 500M RAM, etc. Paid about $1,100 for it.
Looking at my old Toshiba, the power socket in the back was securely moled as part of the case. Not the Matrix, who's socket is only secured by the solder joints on the mother board, and sure enough after 2 days I could hear arching as these solder joints broke loose.
So I took it back to the store and explained the trouble. They said "No problem, we'll just exchange it"
I explained that it was a built-in problem and I wanted to upgrade.
So I chose another tough (And heavy) new Toshiba that displayed $1,800.
Took it to the counter and offered to pay the difference but the clerk said that since it is a replacement there is no additional charge. I asked again and she was sure of it.
Then she handed me two rebate reciepts: $300 store rebate and $100 MFG rebate.
So I got my $1,800 notebook for about $700 + tax

Best Buy in my opinion has the
worst bull-dog, lie-to-your-face, cheating thieving sleazy salesman that would sell out their own mother for a crappy expensive extended warranty, but at least I got a great deal there.
(No extended warranty included. In fact I burned out the mother board and a host of other components with my 3D work 10 months later.....all fixed by Toshiba for free under the MFG warranty)
