How much would you pay for home-made horse treats?

If you were to go to a horse show and see someone selling home-made horse treats, would you buy them? For what price? These would be made with quality products all horse safe and even people safe for that matter. It seems that my horses LOVE them and are always checking my pockets for more. There would be flavor variety of carrot, apple, peanut er, & peppermint. The treats are about 1-2 inch (like when you bake cookies). I would probably sell them 5/bag. If you have any input or ideas I would really appreciate it!!! I was thinking about $2.50/bag to try and cover my costs.
