People in cities all over the world shop in supermarkets. When you enter the supermarket, you see shelves full of food. You walk in the aisles, pushing your shopping cart. You probably hear soft, slow music in the supermarket. This kind of music is playing to relax you and make you walk slowly. Thus, you will probably stay longer and buy more food. Where do you go in the supermarket when you first arrive? Many people go to the meat section first. This area of the store has many different kinds of meat. Some kinds are expensive and others are not. Usually, some kinds of meat are on sale. So it has a special low price. The manager of the store knows where the customers usually enter the meat section. The meat on sale is usually at the other end of the section, away from where the customers enter. If you want to buy this specially priced meat, you have to walk by the more expensive meat first. Maybe you will see something that you want to buy before you reach the cheaper, inexpensive meat. Then you will spend more money in the meat section. The diary section sells milk that is low in fat. Some supermarkets sell three different containers of low-fat milk. Each container looks different, but each contains the same product. One says "1% fat", one says "99% fat free" and one says "low-fat" in big letters and "1%"in very small letters. If you look carefully you can see that all the milk has the same amount of fat, and each container is the same size. The prices of all these three should be the same. However, in many stores these three containers of milk would each have a different price. The store will make more money if a customer chooses the milk that costs the most. Most of the food in supermarkets is very attractive. People often stop to look at the products in attractive containers. But remember, many products will say, "Buy me!". Stop and think which ones are the best value for your money. Supermarket managers make the food attractive so   _   .
