Are you looking for ideas. The fundraising company we have used can give us the cash difference that she would of given on the top prizes. Get a company to donate the Limo ride and take the top seller boy & girl from each grade level to lunch @ McDonalds this should be a total of 5. OR a bike for the top two sellers boy & girl. A VCR for the 2nd most most seller girl & boy. Maybe for the grand prize a Playstation2., books to read for the 3rd prize like 3 a piece. They still get the little rink dink stuff they give a away but making the grand prize better is the best. The class that has the most partipants can have a pizza party one day for lunch. The company we use gives us the print outs so all of this information is already there. The incentives we give are much better. I heard this story once that this family of 3 siblings wanted a game cube I think that's is what's it's called. So they combined all 3 orders from all the kids and guess what they got it. I think to get that one students has to 100 items. I don't know if this is what your looking for.
For our fall fundraiser (our biggest), we are going with a company that does not have any real incentive program for the kids. While the PTO will be providing some incentives for high sales by grade (a $50 bond) and something for the highest sales in the school, I am still on the fence if this is enough to entice the kids to ask "grandma" for an order. What kind of luck have other schools had without a real incentive progam connected to their fundraisers.
