Remember RecycleBank? It's a program that gives points for recycling that can be exchanged for prizes. They're still expanding and chances are they don't have a program set up in your area yet. However, they still allow anybody to join up and start earning points immediately!
If you use code RECYCLEYOURMAGS, you'll get 15 points. Then if you click the “My Account” tab and look at the right side of the page, you should see a banner to join the eBay Green Team. Click it and you'll get an additional 50 points. These points alone won't be enough to get your a nice prize or coupon, but like the Huggies and Pampers programs, I'll probably start posting any codes I come across so that we can all start saving up for the good stuff.
