Recyclebank is a great website to sign up for coupons. You can earn points just by clicking and pledging to do good stuff for the environment. You can get high value coupons for Kashi, Coca-Cola, Aveeno, Dasani and many others. Plus they offer discounts for online purchases and free magazine subscriptions. I got my subscriptions for Cosmopolitan, Redbook and Lucky completely free for a year. Check it out!
