I saw the Yamaha RX-V475 for $349.99 today at the North Olmsted, OH Best Buy. They seemed to have plenty of units available as well. Unfortunately, I had already ordered one at full price ($399.99) from Crutchfield and it will be here on Monday. I did not want to go through the hassle of returning it. Also, I like knowing that Crutchfield is pretty good with their customer service in case I need tech support. So I decided to suffer the $50 loss.
This price is not mentioned online anywhere. Best Buy customer service could not confirm this price either when I called later to check if they still had the deal going but I'm certain I saw that price in store today! $50 off is a pretty good deal considering that I didn't see any other Black Friday deal for this model.
