(Although retailers like Wal-mart are already pushing the envelope with sale prices that used to be reserved for that special time only ...)
Black Friday is also the day that retailers love to fill their stores early -- why else would there be 5:00 AM specials on that day for early birds (and those that haven't gone to sleep yet)? 
For those of us who can't wait for the nice four-color printed flyers ("circulars") to show up in our mail box or paper and instead want a sneak peek at those ads, a number of web sites, like Black Friday 2006, have sprung up.
And after looking at those ads, let me tell you, some of those prices are "In-saaaane" like our boy Crazy Eddy used to say.

The music for the day? How about Steely Dan's "Black Friday?"

Although this is a 2006 article, a lot has changed in the last 2 years. In 2009, shoppers will be able to buy most of their items online on Thanksgiving Day. Avoid the crowds and cold weather and shop from the conforts of home this year. Either pay a little extra to have it shipped or pick it up from the store later in the day after the shoppers have left. Good luck this Black Friday
