I have been using Ebates & ShopAtHome for about 2 years now, and always click through their web site before making my online purchases. I knew I was saving a little here and there, but I just got an email from ShopAtHome letting me know that since I joined I have received nearly $250 in cash back for online purchases I was making anyway! If you are not earning cash back, you need to sign up now!
Sign up at ShopAtHome (every time you hit $20+, you earn a check that quarter)! Also, if you sign up then make any online purchase while earning cash back within 30 days of signing up, you get a $5 bonus!
