We were Neilson families a couple of times, but we didn't get 40 bucks. It was $1 per booklet per how many tv's you had. And they did, indeed, call us on the telephone.
Did on-line surveys too. Those offers I received in the mail, gave you the web site and pin number....once you'd completed the survey (basically asked what web sites you visited), they sent you 5 bucks. Made about 25 dollars doing those, before they realized...this lady doesn't "do" anything but ebay, yorkie talk, a basket board, and google....over and over
every month
