Loved shopping at Campmor growing up, but definitely appreciate this concept. Scouting trips were typically once a year, but need reduced over time as did camping trips.
May also want to check out growth opportunities with other charities. Used to participate in an annual event called Kayak for a Cause with a couple of hundred people. 85% of them needed a kayak for one day... not exactly something everyone is going to purchase.
Good luck!
