We just had had this debate at our Booster Club Meeting this week We settled on $400 which includes a "$100 Spirit Pack" of sweats / t-shirts /shorts etc., which we've sold separately in years past .... Most parents just said "tell me what I owe and don't nickel and dime me!"
Families can pay for some or all of their fees through fundraising. A big one for us is outfield sponsors banners @ $250 ... $100 goes to the athlete's fees. We also do a casino bus trip and a Super Bowl Pool (sell squares)among other things
