BK- Black Friday has a very limited number of certain items - TVs etc that are sold at very low prices. They call them door busters. This is what people line up for. If you aren't interested in any of those items, it is still often a good sale, but usually the biggest sales prices end at noon or around then. With the economy, my guess is there will be sale after sale up until Christmas and then again after Christmas. Just guessing, but it started very early this year.
