Sometimes, though, there are ways to get around the whole raffle being against the rules thing.
Raffles are also illegal in Arkansas. What some orgs do, instead of calling it a raffle, sell something small (some candy, maybe some kind of baked good like a cookie) for $1.00 which entitles the person to a drawing. Make any sense? Like, you would ask someone, "Would you like to buy a rice krispy treat for a dollar and have your name entered into a drawing for this TV?" I can't speak for ALL states, but I know here, you can do that. Because it's not technically gambling because the person buying a chance is also getting something.
However, I would DEFINATELY get the ok before doing that. It may be that you can't do any kind of drawing. It just depends on the area.
