One other thing...

I don't know about best buy specifically, but in the US a lot of retail companies are completely separate entities from their web version for tax purposes. I ran into this when looking for something from Ritz camera and most recently with a squabble over a rebate from Vonage. I bought a router at Circuit City (the physical store). My 175.00 rebate was denied because I didn't buy from a valid retailer. The retailer on the rebate form? circuitcity.com.

The upside is that there was a stipulation I had to be a customer of Vonage for 2 years to be eligible for the full rebate amount. I now have even less reason to stick with them.
