Neilsen Home Scan is now accepting new applicants! Click here to sign up. We are all aware of the Neilsen ratings that shows get, and this is done by the same company. They want to know where you're shopping and what you're buying in return for points.
I have previously participated in this program, but since I do so much shopping, I found it a bit overwhelming to scan each and every purchase I made before putting it away. I did it for about a year, and during the course of this year, got some pretty cool "prizes" for participating!
