Every half gallon’s worth of Stewart’s milk, juice, or drink a customer purchases, they get one punch on their milk club card. After 10 stamps, the customer is entitled to a free half gallon of Stewart’s milk, juice, or drink or a half-priced gallon of milk. If a customer uses one full card for a half-priced gallon, they will receive one stamp on a new card for the half gallon’s worth of milk they paid for at any Stewart’s Shop.
