Are supermarkets designed to persuade us to buy more? When you enter a supermarket, the manager knows better than you, which way you will walk, where you will look, and what will make you buy one product rather than another. The layout of a supermarket is designed to take shoppers around the store, from left to right. Then shoppers will look at all the products. Fresh fruits and vegetables are shown near a supermarket entrance. This gives the idea that only healthy food is sold in the shop. Basic foods that everyone buys like sugar and tea, are not put next to each other. They are kept in different places so customers go past other attractive goods before they find them. In this way, shoppers are encountered to buy products that they do not really need. Customers also buy more when the shelves are full than they are half-empty. They do not like to buy from shelves with few products on them because they feel there is something wrong with those products.
