Walmart’s digital shelf label rollout stirs price gouging debate

America’s largest retailer, Walmart, announced it will roll out digital shelf labels (DSLs) in all its US stores by the end of 2026.

These electronic tags allow stores to update prices instantly across thousands of items, a move retailers say will eliminate the labor-intensive process of manually updating thousands of paper tags.

A Walmart executive speaking to CNBC said the DSLs have cut their pricing duties by 75%, freeing up time to help customers.

Walmart isn’t alone; several retailers, including Kroger, have implemented or are testing electronic shelf tags to increase store efficiency.

However, the rapid adoption of this technology has sparked a political firestorm, with critics saying it is a gateway to dynamic pricing in grocery aisles, similar to flight ticket and ride-share bookings.

Lawmakers, led by Senator Ben Ray Lujan, have introduced the Stop Price Gouging in Grocery Stores Act, which seeks to ban digital tags in large retail spaces to prevent algorithmic price hikes during peak hours.

Retailers claim that DSLs ensure price accuracy and facilitate real-time discounts on perishable goods, thereby reducing waste.

In 2024, Wendy’s announced plans to update its digital menu boards to reflect real-time pricing changes, which drew mass public backlash and a boycott, claiming it was price gouging.

The fast food chain had to clarify that it was using the technology to update discounts, not to increase menu prices.
