Impulse Buying

An impulse purchase is an unplanned or otherwise spontaneous purchase. One who tends to make such purchases is referred to as an impulse buyer.Marketers and retailers tend to exploit these impulses which are tied to the basic need for instant gratification. For example, a shopper in a supermarket might not specifically be shopping for confectionary. However, candy, gum,  mints and chocolate are prominently displayed at the checkout aisles to trigger impulse buyers to buy what they might not have otherwise considered. Alternatively, impulse buying can occur when a potential consumer spots something related to a product that stirs a particular passion in them, such as seeing a certain country's flag on the cover of a certain DVD. Sale items are displayed in much the same fashion.
