The next busiest day after black friday is the return the shit you bought Saturday. I spoke to a guy at best buy and he was telling me the name brand shit on Sale on Friday is actually manufactured just for Black Friday. It is lesser quality hence a cheaper price. he says that people go and see a Toshiba on display and think it looks good, then see a Toshiba on sale for $250 and go buy it, take it home and realize it looks like shit and take it back on Saturday. These stores will only report on the sales though. So Best Buy will make a claim if took in $250 million on Black Friday to help boost stock sales but they won't show that they took in $175 in returns the next day.
