    You need some bread and milk. But half an hour later, you leave the supermarket with a trolley (手推车) full of food. What games do supermarkets play to make us spend so much money?

The tricks start just when you go into the supermarkets and, of course, a small basket would be fine, but all they have are trolleys. And of course the problem with a trolley is that it looks sad and lonely with just one or two products inside. So we may fill it with something. In fact, supermarket trolleys are actually getting bigger so that we buy more.

Of course, many people shop in supermarkets because they think everything is cheaper than in other shops. So supermarkets offer very cheap prices on some things but then have higher prices for other products. One new trick is to put red stickers (标签) on products. Customers usually connect red stickers with lower prices so the red stickers are easy to be noticed, even when there is no reduction! Interestingly, this trick appears to work more with men than with women.

There is a story behind the position of everything in the supermarket. For example, customers often go only to buy milk. So they put it right at the back, forcing you to go past hundreds of shelves full of other products. The position of products on each shelf is also important. The most expensive products are usually at eye-level so you see these immediately. The exception is anything that children might like. These products are on lower shelves so that kids see them.

Apart from what you see and smell in a supermarket, what about what you listen to? In most supermarkets they have soft, slow music. It’s so relaxing that you slow down and spend more time (and money) in the store. You also move more slowly when the supermarket is busy. Experts suggest it’s better to shop when it’s quieter, on a Monday or a Tuesday for example. And be careful with queues at the checkouts. These are sometimes deliberate, to make you buy something from the checkout shelves while you wait.

So, next time you go into your local supermarket, remember these tricks and see if you can come with just the things you went for.
