Great Lake Scrip, based in Michigan, seems to be a good one to do business with. You may want to check them out. There's one in CA that has recently had several problems--well mentioned on this board over the spring/summer.
We have a parochial school that sells scrip. It is a huge operation. They hired a parent to do the job. We also have a public school that sells scrip. They have a long-term loyal woman that handles the very fine-tuned program. She's volunteer, with several helpers. Both are huge programs, making several thousand dollars a year.
Critter, thank you for the information. Regarding the school you know of personally, do you know what kind or how much of an incentive they give their coordinator?
If anyone else has any feedback on this, I'd love to hear it too. Thanks!
