The era of the paper price tag is ending. Major retailers are rapidly replacing static paper labels with Electronic Shelf Labels (ESLs)—digital screens that allow stores to change prices instantly with the click of a button. While stores claim this technology improves efficiency and accuracy, consumer advocates warn it opens the door to “dynamic pricing.” This practice, similar to Uber’s surge pricing, allows retailers to raise prices during peak hours or periods of high demand. In 2026, shoppers need new strategies to ensure they don’t unknowingly pay a premium simply because they shopped at the wrong time.
