A friend’s gym was very successful by doing a raffle for a major amount of gear and classes, (ex Nfinity bags, Vegas bows, tumbling class or camp vouchers, free privates, Rebel gear, worlds team clothes, stunt stands, mats, etc). People all over were entering (if you weren’t local then I believe they gave you an amazon gift card instead of the classes/privates) and I want to say they raised about $10k for around $2,000 worth in prizes. Plus the gym gained loads of publicity from it! ;)I’m not sure how shipping everything worked out if the winner wasn’t local, but I’d imagine in that case (since they were giving new items) that they would just ship the products directly from the producer to the prize winners.
We’ve seen gym sleepovers/lock-ins/parent night outs be very popular as well, especially if you have a selling point like idols/worlds athletes being there.
Hope these might help!
