It has been found that fewer than one shopper in five makes a complete shopping list before going to the store. The reason for this is that seven out of ten of today’s purchases are decided in stores where shoppers tend towards impulse buying. Buying groceries on impulse has risen for the past forty years, and this rise has coincided with the growth of self-service shopping. However, in grocery stores where clerks wait on customers, there is much less impulse buying. It is hard for people to buy on impulse if they have to address a clerk.

Psychologists have joined forces with merchandising experts. It is their job to persuade people to buy products which they may not need or even want until they see them attractively presented. It was discovered by the psychologists that shoppers want help with their purchases. Having so many choices confuses them, but they are affected most by attractive package designs. Attraction also depends a lot on the products position on the shelf, however, and persuading shoppers to buy is easier when the product is located at eye-level.
