I think the point is that it gives you stores/merchants that are near you. The premise behind it is the fact that people likely do not want to travel long distances to buy everyday items or even large purchases so if they can find a store closer to where they are at the time they are looking they are more likely to visit the store and spend their bitcoin there.
