Memory-Based Store Price Judgments: The Role of Knowledge and Shopping Experience

This paper investigates the processes underlying consumers’ memory-based store price judgments. The numerosity heuristic implies that the greater the number of relatively lower priced products at a store that consumers can recall, the lower will be their overall price image of the store. That is, people use the number of recalled low-price products to judge the overall store price image. We show that this expectation holds only for knowledgeable consumers. Instead, less knowledgeable consumers use the ease with which low-price products are recalled (i.e., the availability heuristic) as a cue to make store price judgments. Therefore, the fewer low-price products they recall, the easier their recall task, and the lower their price perceptions of the store.
