Meijer just started a Meijer Community Rewards card. Your organization gets a percentage of your monthly spending, you have to spend at least $100 in a month. They donate 1-4% depending on your monthly total. Our first month was in December and we only had 17 cardholders and we are going to get a check for $51.
In California the local Safeway chans (Safeway, Vons, Pavillions) use escrip as their receipt program. It is tied to their customer loyalty cards. We make several thousand dollars each year off this.
ShopRite has a program where we have shopper cards and amounts are registered every time we use the cards. The program runs from September to April. They have a catalog that we can redeem our "receipt amounts" for different items. The items range from crayons to computers. The great thing is anyone can register their card for any school that they choose.
We also use Kash for Kids, Schoolpop, Boxtops, and Target.
In Northeast Pennsylvania we have Price Chopper that has a program and also Redner's Warehouse Markets give 1% of total receipts to any non profit group.
Giant Eagle receipts (actually we have shopper cards and amounts are registered every time we use the cards). I think it's associated with Apples for Computers (gianteagle.com). We usually earn 1 or 2 computers per year.
Kash for Kids and Office Depot
We send in cartridges for money or redeem for reams of paper.
