The day after Thanksgiving, Friday, is Black Friday. Its also known to be the first official day for Christmas shopping. During this day, many prices are cut down on many products. Including popular items.
For shoppers, I think its called "Blitz".
I am am spending about $2000 on Christmas presents that day, minus the Wii. I had to be on a call list to get that. I has to pick it up a month ago since they are backordered.
