The primary catchment area refers to the geographic region where a point of sale is most attractive, encompassing consumers who regularly purchase its products or services. It is defined based on the maximum travel time customers are willing to make, which varies depending on the type of store; for example, less than 10 minutes for a hypermarket or up to 30 minutes for a specialty retailer. This area is essential to marketing strategy, as it allows for effective audience targeting and the adaptation of sales efforts.
