Well, I have to thank fan Patti M.M., who let me know about an other freebie for good grades.
Chuck E. Cheese will give customers up to 15 free tokens for good grades. Kids must bring their report cards to the restaurant. You can learn more about the program here and find your closest restaurant here.
I'm checking out a few others that Patti M.M. suggested, so check back later for more good grades rewards!
