What is the average cost to join the fitness franchise Curves?

I am really interested in joining Curves. It seems like it will fit into my schedule and I only have a small amount of weight to lose. I just want to know how much it would be?What is the average cost to join the fitness franchise Curves?I pay 31.99 monthly and it comes out of my checking account directly each month, otherwise it was $10 more per month. I joined when they were doing a special, i signed up for their diet class and so i was enrolled for only $65. Try to sign up during a promotion, they are always having them, otherwise you might pay upwards of $150 to start. Hope this helps, I love Curves!
