Kroger has been swapping out traditional paper price tags for electronic shelf labels across roughly 500 stores nationwide, and the company's customers are not happy about it. The grocery giant says the technology saves time, cuts paper waste, and frees workers to help shoppers. Critics see something else: a tool that could let the chain change prices on the fly, adjusting what families pay for milk, bread, and eggs based on the time of day, the weather, or how many people are in the store.
Interim CEO Ron Sargent recently confirmed the expansion is ongoing. The technology, first tested in 2018, lets managers update prices across an entire store in seconds from a computer, a process that once required employees to print, sort, and physically swap thousands of paper labels.
That speed is exactly what worries shoppers already stretched thin by years of rising grocery costs. The backlash has been building online, and at least two U.S. senators have demanded answers from the company about whether the labels could open the door to dynamic pricing on everyday essentials.
Electronic shelf labels, or ESLs, are small digital displays mounted on store shelves in place of the familiar paper tags. The Daily Mail reported that Kroger has expanded the system to hundreds of locations, with the total reaching roughly 500 stores across the country. The labels can be updated remotely, allowing prices to be changed across an entire store in seconds.
Walmart, which has also adopted the technology, has said that updating traditional paper shelf labels can take employees up to two days every week. Digital systems cut that to minutes.
The efficiency argument is straightforward. But for consumers who have watched grocery prices climb steadily in recent years, the idea that a store can reprice its entire inventory with a few keystrokes does not inspire confidence. It raises a basic question: If the technology makes it easy to lower prices quickly, it also makes it easy to raise them.
One frustrated customer posted on X: "Don't buy anything with a digital price tag on it." The same user added: "We can stop this nonsense real soon."
Kroger has repeatedly denied using electronic shelf labels for surge pricing. The company says the technology is designed to improve efficiency, reduce paper waste, improve price accuracy, and let employees focus on customer service rather than manual price changes.
Sargent confirmed the rollout on a recent conference call, stating plainly:
"Electronic shelf tags, we are rolling out across the company."
Industry groups have largely echoed Kroger's framing. Doug Baker, vice president of industry relations for FMI, The Food Industry Association, said the grocery sector sees ESLs as a natural step forward.
"The grocery industry is embracing the technology. ESLs are an important part of the future."
But denials and industry talking points have done little to quiet the criticism. The concern is not necessarily that Kroger is using surge pricing today. It is that the technology makes it possible tomorrow, and that nothing in the current arrangement prevents it.
Kroger has already been under pressure to hold the line on prices. The chain recently moved to slash prices on thousands of items as inflation-weary shoppers fled to discount rivals. Rolling out a pricing system that looks, to many customers, like a tool for raising costs, even if the company insists otherwise, is a strange way to rebuild trust.
The political scrutiny arrived before the backlash went viral. Senators Elizabeth Warren and Bob Casey previously demanded answers from Kroger, warning in a letter that the labels could facilitate a shift toward dynamic pricing on everyday essentials.
"These digital price tags may enable Kroger and other grocery chains to transition to dynamic pricing."
The senators warned that retailers could potentially adjust prices based on factors such as time of day, weather, or shopping demand, the same model that consumers already encounter with ride-sharing apps and airline tickets, but applied to groceries.
Whether or not one agrees with Warren and Casey on much else, the underlying concern is not partisan. Families buying groceries are not booking hotel rooms. They are buying necessities. The idea that a gallon of milk might cost more at 5:30 p.m. on a Tuesday than at 10:00 a.m. on a Wednesday strikes most people as fundamentally unfair, and rightly so.
The political pressure is not limited to Capitol Hill. New Jersey has moved to ban algorithm-driven grocery pricing at retailers like Walmart and Kroger, reflecting a growing bipartisan appetite to draw a line before the technology outpaces the rules.
Neil Saunders, a retail analyst at Global Data, told the Daily Mail that stores adopting ESLs will need to exercise restraint if they want to avoid a serious consumer backlash.
"Retailers would have to be very careful not to adjust pricing too much otherwise it could undermine their price competitiveness and reduce consumer trust in them."
That is a polite way of saying what shoppers already feel: if the price on the shelf changes every time you look away, you stop trusting the store. And once trust is gone, so are the customers.
The broader grocery landscape only sharpens the stakes. The failed Kroger-Albertsons merger already rattled the industry, leaving workers and communities uncertain about the future of their local stores. Meanwhile, independent grocers, the kind that still put paper tags on shelves and know their customers by name, continue to struggle against corporate chains with deeper pockets and more sophisticated pricing tools. Some, like a family-owned New Jersey grocery store that closed after 50 years, simply cannot compete.
Kroger's stated reasons for adopting ESLs, efficiency, accuracy, reduced waste, are plausible on their face. No one doubts that printing and replacing paper tags is tedious work. No one objects to employees spending more time helping customers instead of swapping labels.
But the company has not addressed the harder question: What guardrails, if any, prevent Kroger from using the technology for dynamic pricing in the future? A denial is not a policy. A press statement is not a binding commitment. And a technology that can reprice an entire store in seconds is a technology that creates temptation.
Kroger began testing ESLs in 2018. Seven years later, the system is in roughly 500 stores and expanding. The company's interim CEO confirmed the rollout is continuing. Yet the company has offered no public framework, no written policy, no contractual promise to customers, that limits how the labels will be used.
That gap between capability and accountability is where the real concern lives. Shoppers are not opposed to technology. They are opposed to being treated like airline passengers at the checkout line.
When a grocery chain can change every price in the building before you finish your shopping trip, the least it owes its customers is a straight answer about whether it ever will.
