Black Friday Ads are a must for the savvy shopping saver.

Wiki:

Black Friday is the Friday after Thanksgiving in the United States, where it is the beginning of the traditional Christmas shopping season. Since Thanksgiving falls on the fourth Thursday in November in the United States, Black Friday may be as early as the 23rd and as late as the 29th of November.

Black Friday is not an official holiday, but many employees take the day off, which increases the number of potential shoppers. Retailers often decorate for the Christmas season weeks beforehand. Many retailers open very early (typically 5 am or even earlier) and offer doorbuster deals and loss leaders to draw people to their stores. Although Black Friday, as the first shopping day after Thanksgiving, has served as the unofficial beginning of the Christmas season at least since the start of the modern Macy's Thanksgiving Day Parade in 1924, the term "Black Friday" has been traced back only to the 1960s.

It is best to start at webpages like blackfriday.com and bfads.net, which focus entirely on this day after Thanksgiving.

Like it says in the video, try to go shopping the last day before Black Friday after 6pm (this is the time where the price changes are usually done), as this is probably the only time where you can snag a real door buster.
