The $10 off a $10 purchase from Schwan’s is still available- for more information see my post HERE. This offer is for new customers only.
The Nielson Panel is still accepting applications HERE. Last time this offer went incredibly fast but this time around they are still looking for families to participate in test panels. They will send you a scanner and you scan your purchases and in exchange you get free rewards- some pretty good stuff is my understanding. This is the same AC Nielson that does the TV ratings.
