Point of Purchase - POP

Investopedia explains Point of Purchase - POP
In recent years, the point of purchase for products and services has become an important focus for marketers, because consumers tend to make purchasing decisions on very high-margin products or services at these strategic locations. Points of purchase may be real, as in the case of a "brick and mortar" store, or virtual, as in the case of an electronic retailer that sells goods and services over the internet.
