When we talk about a purchase illustrating a buying habit, we are referring to a purchase made automatically, without real thought or particular impulse, simply because it is part of an established routine. This type of purchase is characterized by its regular repetition during shopping trips, without the consumer questioning its relevance or intrinsic value. It can result from loyalty by inertia, manifesting as repeated purchases of the same product or brand, without being motivated by any real preference or satisfaction with it. The expression “conditioned purchase” is sometimes used to describe this phenomenon.
