Today in the mail I got this really awesome reusable shopping bag. This was a promotion through Stouffers. You earned points which you could redeem for a donation to Feeding America and earn yourself a reusable shopping bag. The bonus was, you earned enough points just signing up to earn the bag! The extra bonus is, they received an overwhelming response and were able to donate 1.8 million meals in the first donation and an additional 95,472 meals through the second effort, so far.
I believe the bag promotion is over, but the dinner club is still active and you can enter points from meals to earn other rewards. You can register here : Stouffer's Dinner Club
