Yeah, so why u dont make them actual contests. atleast put a tiny bit of trivia or something. Or u could get smart and do fun stuff like put 10 million on a leet and tell everyone to go leet hunting, but thats best for events not regular DJing. Also item prices is more fun than cash, even if u only get cash as donation u could shop some items and give those out instead.
