Last fall, Emily Krieger, a mother in Bozeman, Montana, began to wonder about the unending fees she was paying to provide her two children lunch money at their local public school.

A cafeteria lunch at Emily Dickinson Elementary School, where Krieger’s children attend, costs $2.25, plus $1 for a carton of milk. Yet last year, the cost of loading money onto students’ meal accounts — which are managed by a website called MySchoolBucks — increased to $3.25 per transaction. The fee had grown larger than the cost of an entire meal.

“It caught my attention,” Krieger told The Lever. On the MySchoolBucks website, the $3.25 charge was called a “program fee.” But that money, Krieger learned, wasn’t going toward her children’s school.
