Every month, a reviewer is chosen at random who submitted a prior month review regardless of their review content. The winning reviewer is contacted by email and notified of their winnings and his or her $100 VISA gift card is sent to their address of choice. You can review rules and guidelines on our Review Contest Rules Page.
