Milk delivery is a delivery service dedicated to supplying milk, typically in bottles or cartons, to customers' homes. This service is performed by a milkman, milkwoman, or milk deliverer. (In contrast, a cowman or milkmaid tends to cows.) The delivery route is a milk route or milk run.
Home milk delivery was common in many countries until the second half of the 20th century, when modern supermarkets and household refrigeration made it possible for consumers to buy and store milk on demand. Today, milk delivery still exists a niche market in some countries.[1][2]
