Paying subscribers can get physical rewards in the mail by exchanging their virtual tickets for books or toys. We believe these mechanisms can motivate children to remember to study and practice. That being said, the rewards we offer will be regularly changing. We do not guarantee that we will have in stock any particular toy. Rather we do our best to send out rewards that are at least similar in nature to the ones the students have an interest in. We minimize the chance of fraud by capping the earnable tickets each month. We do not operate like a store and so we do not process product returns.
