Join the National Consumer Panel (NCP) for free and earn rewards by doing something unique.  The National Consumer panel is a panel made up of consumers whose opinions help manufacturers and retailers make decisions on what products to develop or improve and sell in the market.  You will be mailed a handheld scanner or granted access to use their APP. Then, you’ll use the scanner to scan the barcodes on all products you purchase during any shopping trip you or someone in your household makes.

I did this for few years, but my extreme shopping trips don’t necessarily reflect the typical shopper, so we parted ways.  Scanning is really easy (they’re like grocery store scanners) and it’s kind of fun!
