Before you accept a product for 10 to 20 percent of the proceeds, think about it for awhile. Some companies have sliding scales and you will have to predict how well you think you can do. Schools that have sold pies at Thanksgiving, plants at Mother's Day, and their very own cookbook at Open House. Many of the commercial companies that offer sales programs to schools often push incentive prizes for students. Be careful here.
Parents react negatively to incentive prizes.
Alternatively, you might wish to provide your own merchandise to sell, such as school T-shirts or books from your book fair. Or reward a classroom with a pizza or popcorn party. Try Super Print or Kid Pix and use a color printer to make your proofs. Print Shop Deluxe will print the calendar pages for you. You can use a simple but powerful program like The Learning Company's Student Writing and Publishing Center for kids to create pages of a cookbook of family recipes.
