I have a small town HS baseball association in my neck of the woods that does an annual gun raffle. A variety of 25 hunting rifles and shotguns given away, $100 per ticket, only 300 tickets printed and sold. $30K revenue for what, maybe, $8-12K worth of guns and minimal work. This wouldn't work for every organization, but it's a pretty good fundraiser for these guys, and they know their base.
