Have you ever noticed that your local grocery store has all the milk and eggs at the very opposite end of the store as the entrance? This may be because you will have to walk by more items before grabbing the ones you want, which means you are more likely to buy more.
Product manufacturers can also pay grocery stores to place their items on the middle shelves since people spend more time looking at items placed at eye-level, and hence are more likely to purchase them. In aisles with products that may appeal to children, these items may be placed at their eye-level, i.e. on the lower shelves.
It would seem that supermarkets have spent lots of money on hiring psychologists and marketers to make more money from consumers – and it seems the investment was worthwhile. They go so far as to analyze the probability of turning left versus right upon entering a store so that they can place higher priced items on the path most traveled – so that by the time that you have made your way through most of the store you will be getting to the lower cost items. Based on having seen the higher priced items earlier, the lower prices on the smaller items comparatively seem like a bargain, and you are more likely to purchase more of both if you start by seeing the higher priced items first.
