Historically, Black Friday, the day after Thanksgiving, is the day that the retail industry gets out of the red financially speaking. In the past the allure of a good deal was enough to bring customers in to buy your wares.
Over the past few years, in an attempt to entice customers, businesses have been opening earlier and staying open later. Now we have gotten to the point where some aren't even finished with their turkey dinner before doors are opening with 'door buster' deals. These people are insane.
Just look at the pics from the early hours of this years Black Friday.
