If you're looking for a unique program that will allow you to earn points and make a difference in consumer products, here's one! Join Nielsen Home Scan Consumer Panel - Earn valuable points, which are redeemable for electronics, household items, jewelry, toy, gift cards, and more. Panelists must have a rotary Land Line Phone, not VOIP.
It's pretty easy, but might be a little time consuming. You just scan the products you purchase and then once a week, you upload the information. Each upload earns you points based on various factors. I've personally done this before and enjoyed it, but backed off of it. I might be up for doing it again soon!
