Amazon.com Discount Page.

Amazon.com has a Promotion page (link above) which shows you all the promotions going on at their site. Right now they have a buy 3 get 1 free promotion for different categories. What is nice is they also will tell you all the products they are selling that have rebates attached to them along with products that will give you bonus items. This page has saved me a lot of time, so now instead of scouring for deals I have a great starting point! Enjoy!
