Discount on sports

I forgot to mention when I listed all the sports my children are in that I get a discount at the YMCA. I applied for it for low-income and I only have to pay 50% of all classes. We are members and so my memberships is 50% too. So, to sign up one child for football it is about $140 for non-members and $65 for members and then we pay 1/2 of that. Some classes are free too, like ballet.
