DD1 dances at two different dance schools. The shows for one (which happen every two years) tickets are usually around £11 with £2 reduction for concessions. They happen at a local theatre.
Her other dance school have a show coming up in a similar local theatre and they are charging £17.50 with no concessions. 
DD2 has done many youth theatre shows at the same theatre and the tickets are never more than £13.
Am I right in thinking this other dance school are taking the piss?
Two members of my family have made their excuses as to why they are unable to come and I am pretty sure it's the cost.
It's a bloody dance school not the flippin' National Ballet! 
(Oh and it's nothing to do with subsidising the cost of the costumes as we are paying an arm and a leg for those too...)
