For those who read at night and catch this before the day changes in Seattle, you can get a great deal on Melissa & Doug Toys, as Amazon has many of them at 50% off as a Gold Box Deal
In the (paper) book world, Amazon has some decent discounts on their Best Books of Year: Top 100 Picks for 2012 and Editors' Gift Picks, but a really good discount on children's books with 50 Books, Just $5 Each, all of which are published by one of Amazon's publishing companies. The top two have list prices of over $15, so there are some real savings (I know kids picture books can be crazy expensive). Be sure to click the Adult Books tab - 34 of the titles are for the big kids in the household.
If you are wondering how everyone knows when some of the great deals in music, video games, movies & tv, computer software and MP3 players & player accessories, then be sure to bookmark these Black Friday Deals Calendar links. For other categories, you do have to check the Black Friday Week page each day, but you can plan a bit better with the calendars, where they exist.
