My husband and I used to do the Nielsen Home Scan Consumer Panel. They sent us a little handheld scanner (like stores use), and we scanned all our purchases for them.
It was pretty fun to do. We got to tell them about our shopping tenancies. And in return we earned valuable points that we could redeem for electronics, household items, jewelry, toys, gift cards, and more.
What did we use our points on? Well, we saved up and used them to purchase some items for our son for Christmas that year. A great way to put a little work in and get great rewards in return.
