Why the Milk Is Always at the Back of the Store

Six items on the list. Twelve on the receipt. Ninety-four dollars for milk, eggs and bread. That is not weak willpower - that is supermarket psychology, and the grocery store layout was built for exactly this. Up to 62% of grocery store revenue comes from purchases that were never on anyone's list. 76% of purchase decisions are made inside the store, not before arrival. The science behind the supermarket tricks in this video is sixty years old and very well funded. In this video: why the milk sits as far from the door as physically possible; what slow background music did to sales in a 1982 study every chain still knows; why the cart is bigger than it needs to be; what the loyalty card actually buys; and the one habit that cuts spending without any willpower at all. Every price has a winner. It usually isn't you.
