An independent supermarket in suburban Chicago is using a promotion that benefits a local school and their store. Every month, the school buys $20,000 worth of $10 cash cards (2,000 cards) that are as good as money in the store. They get a 5 percent discount, or $1,000 off, which the school keeps for special projects and general expenses. The school has parents who have committed to purchasing all the cash cards every month, so that the school quickly gets its investment back, including their $1,000. Because the families need to buy groceries every month anyway, they now shop at that supermarket and use the cash cards to pay for part of their purchases. The store then resells the numbered cash cards
back to the school the following month, and the cycle goes on.
The supermarket is getting a lot of customers that probably would have gone to the bigger national stores, and the additional business easily pays for the 5 percent discount. The store also makes some of the discount back because people never redeem all the cards, and people buy more than $10 worth of groceries per trip. The store is helping the school and promoting their business at the same time.
You could do something similar with several schools at one time or with any other nonprofit organizations. Have signs in your store inviting anyone interested to inquire about participation in a program that can benefit both of you.
