The 2011 SunnyD BookSpree allows teachers to collect labels (from parents, friends, and acquaintances) from eligible SunnyD products. Teachers then redeem 20 labels at SunnyD in return for 20 free books. To qualify, in one envelope, the teacher of an eligible class must submit 20 proofs with a fully completed official entry form. Twenty age-appropriate books of the sponsor’s choosing will be provided for each valid submission.
