We went to look at a Stagecoach school.
£27/week. The owner had his Porsche parked outside in the disabled space (there were plenty of free spaces, I presume this is a Porsche thing that you park in the disabled space not to get your car scratched or something, I don't really know.)
16 children being taught to sing by one teacher.
DS was a member of a non-profit choir previously. There were about 10 children, three qualified volunteer staff and it cost less than £27 for the whole term.
He also does Scouts, again it costs less than £27 for the whole term, they do lots of activities and again several volunteers giving their time without payment.
From what I can see people don't really appreciate or respect the time given by people running these groups, and would rather sign up in droves (apparently Stagecoach are beating people off with a stick) for expensive and inferior profit-making groups.
