One hour prior to sales is not nearly enough if you want the good stuff. My brothers and I went to Best Buy two years ago and at 6:00 the line went all around the parking lot. This is no exaggeration.

Circuit City has a $400 laptop that is $300 after rebate.
Best Buy has a $380 laptop, but there black friday ad has been removed from all black friday sites.
Staples also has a $400 laptop.
I'm thinking of getting in line at 4:00 or 5:00am... Crazy? Maybe.
