Clearance is often store-specific
Stores may move through seasonal or discontinued inventory at different speeds. One location can mark down an item while another keeps the regular price.
Distance changes the value
A lower price forty miles away is not automatically better than a modest discount nearby. Fuel, time, tolls and availability risk reduce the practical savings.
One report does not define a region
A single observed price is evidence for that store and time. A regional pattern requires multiple matching observations.
Compare exact configurations
Retailer-exclusive bundles and local assortments can look identical in search results. Model and pack details must match before calling the difference a price gap.
