We have a local radio station that is having a Christmas Cash contest. They want our bank to provide the $500 cash prize. Their listeners will send in Christmas Cards to the radio station and on December 22 they will draw a winner. The winner will receive $500 cash that will be presented to them in our bank lobby by a bank employee. In return our bank will receive radio commercials, name recognition as the cash sponsor and on-air and social media posts. They would also like to place a collection box in our bank lobby to collect the Christmas cards. I feel like this is part of a lottery and we should not participate. Am I wrong?
