I recently bought a dishwasher. I did not receive a email (which I was promised) telling me when my delivery date was, nor did I receive a phone call. What I did get was a call informing me they were 15 - 20 minutes from my house and on their way to deliver and install.
Bestbuy should somehow make this information available to us on their web site. A customer could login to their BestBuy.com account to confirm an appointment rather than spend time calling in.
