I found a very effective way to handle the folks who come in the door with their hands out. I tell them we have a supporter program, where we will support them with 5% of all purchases made by their members.
If they want, we'll even print up cards for them, but all they actually have to do is have their members mention the group before we ring the sale and the P-O-S system will track the purchase. We will then mail them a check when the balance reaches $ 50 or every quarter.
Little did I realize that 30 years ago, when I came up with this that I was setting up what would in the future be called an affiliate program.
