The American grocery aisle is undergoing a massive technological overhaul. For decades, retail pricing moved slowly. Employees walked the aisles pulling paper tags by hand to run a weekly sale. That manual process is officially ending. Walmart is currently rolling out electronic shelf labels to all 4600 of its domestic stores by the end of 2026. These digital tags connect directly to a centralized computer system. The technology allows the largest retailer in the world to change the price of 120,000 items in a matter of minutes. This shift is sparking a fierce national debate about how dynamic pricing affects your household budget.
