This site charges a dime a diecut, they have many choices, the money earned goes to a private school, there is a $1 s&h charge for orders up to $15...the good part is they trade the diecuts for Boxtops for Ed, Campbells Labels for Ed, Tyson Project A+, and other things. So the diecuts would only cost you $1 for s&h with the boxtops or lables.
