There are no hidden costs. It is completely free! A primary incentive for me, as a teacher, is to extend my program to encourage and improve reading beyond the walls of my classroom. Having the Book Club implemented by educational professionals is the ideal way to insure its success.
I offer free prizes to encourage students to reach their reading goals. RewardZone merchandise is an optional goal setting enhancement for Book Club families. Proceeds from its purchase gowards improving the site and charity. I do offer discounted tee shirts and merchandise samplers to schools to promote the Reward Zone.
