Although the driving factor for many schools to buy milk-vending machines was better nutrition for kids many are learning that it comes with an added benefit — profitability.

Take for example Strongsville High School in Northeast Ohio. The milk-vending machine in the cafeteria paid for itself in just one month and cleared $11,000 in five months. In fact, the food service director for the school credits the milk-vending machine — with sales of $120 per day — with keeping her budget in the black.

The school bought the vending machine with the help of a $1,000 grant from the American Dairy Association and Dairy Council Mideast. So far, the group has helped 12 school districts in Northeast Ohio purchase milk-vending machines.
