Reasonable cost per class?

I started Pilates about a year ago at a reformer studio nearby. At the time it was $50 per class. About 6 months ago it went up to $55 and I just saw today they increased it to $60 per class. They do offer memberships/packages but I prefer to pay per class because of the commitment and it really only saves me about $3 per class when I do the math. The extra $5 isn’t going to break the bank but it’s not like the class itself is changing so I am frustrated by another jump in price.

I’m curious what everyone else pays per class?
