One embodiment provides a method for evaluating transaction data to determine point of location usage. This could be, for example, to determine where customers are mostly likely to shop before or after shopping at a given merchant. For instance, the method could show the percentage of customers that shop at certain types of stores during a time period right before or after shopping at the merchant's location. As another example, the method could be used to determine when a merchant's customer makes a purchase at the merchant's store, then makes a purchase at a competing merchant's store within a specified time.
