SWEEPSTAKES.

i won at the kraft sweepstakes they had (not sure if it's still ongoing...altho i'd presume so)-and got $15.00 worth of free products....i knew my constant entering of contests would pay off, haha. Here's a list of a few i've found.
There's actually a website you can go to ( http://www.online-sweepstakes.com/ ) that lists them all--the site, the prize, and the last day to enter.
It also categorizes them in different catergories such as how many times you can enter, and what the prize type is!
