I think you're describing the chaos at Wal-Mart. Have you folks seen some videos about W-M's BF's? Calling them "animals" would not even describe them.One thing I learned at Fry's Black Friday is that 80-year old ladies will wrestle for "rebound" positioning and box you out. They can get very physical so watch out!
On the other hand, Best Buy does a ticketing system for FIFO queue instead of Fry's Free-For-All.
