It's a lot cheaper than any sports or music program and lasts 9 months out of the year (depending on the Pack - some are all year around) and they get so much more out of it! Both of my boys are Scouts and have been since Tiger Cub. My oldest is about to Eagle and my youngest is moving along quite well too. They have matured in ways no other program could have impacted them. I am so proud of the young men they are becoming and I give Scouts quite a bit of credit in that. Scouts aren't for everyone but it was a right fit for our family. My husband is also a leader so we are deeply imbedded in Scouts.
To answer your question - it was about 100.00 year w/ dues and camping fees + the initial cost of the uniform. It wasn't all paid at once.
