PriceGap asks whether the store is pricing you differently

Field notes

PriceGap describes a browser-side comparison: it reads the shopper’s product page, reloads the same address without cookies or login, and compares item-plus-delivery totals when both are visible. The page gives a concrete example of $22.64 versus $26.11 for a 10-pack of moving boxes, attributing the difference to a business discount. It also lists blind spots, including quantity tiers and prices that change by the hour. The extension and public evidence wall are described as forthcoming rather than verified here.
