I was super excited when I was chosen to be a panelists for Nielsen Homescan. I buy my groceries, scan the barcodes with the provided scanner, answer a few questions, and at the end of each week I send the data. That is all there is to it and I earn rewards along the way! My husband and I used it for the first time yesterday and it was so simple. Not very time consuming like I thought it would be. I will let you know how it goes.
