For A Three Dollar Raffle Ticket

The ticket itself also provides admission to an event but I want reward those who buy tickets in advance by entering their name in a drawing. In asking this question I wanted to know what we could offer for those who don't plan to attend but just may be swayed by the prizes offered up even though they won't be there. I need to know if you are gonna spend three dollars on a raffle ticket what BIG prize would you expect to win.
