Pay to Play Highschool Football?

I have a coworker who's son plays for Owasso football. She showed me a letter they sent home to parents about "players fees" $400 being due before they can play. It's not for a summer camp or some specialty training. Is this normal for all high schools locally?

I grew up in Dallas and I can't imagine my parents ever being able to afford that, I 100% wouldn't of been able to play.

I've been told that if you don't pay the coaches will bench you until all "player fees" are handled. What????
