Not Best Buy related but I tried purchasing an elliptical online from Amazon along with assembly. One company does the shipment and a third party does the assembly. The assembly guy cancelled on me because it was raining (not really hard) and he couldn't come out at a reasonable time.

I cancelled the assembly, had the box returned to Amazon (of course its not their regular shipping). I then ordered from Sears. They came on time with the equipment and they did the assembly.

Back on topic. I'm debating whether to use Geek Squad to mount my TV (I have no mechanical skills) or purchase it through Amazon for half the cost.
