Black Friday, the day after Thanksgiving, is traditionally the start of the Christmas Holiday shopping season in the US. Many stores open early 3-5 AM and have big sales on that day. It's a day that any wise man never leaves the house; unless his wife forces him to go and carry things.
Yeah, if you come over tot he US you can buy a super alienware computer for $100. Well not really, but at least the usual 20% is better than nothing for the C-store. Besides, I would say most of the greatly discounted items this year is all the stupid crap that they couldn't sell during the year. Most disappointing black Friday that I have ever seen. Not even worth going out to shop.
