The letter landed on a Friday afternoon, and its purpose was to stop a rumor before it hardened. Walmart, the retailer said, had begun hanging digital price tags in its stores, and customers had started asking a pointed question: was the company going to use them, and its new AI shopping assistant, to charge different people different prices?
John Furner, who runs Walmart’s U.S. business as president and chief executive, answered in a note posted to customers and employees on September 26. The company, he wrote, would not use the technology to set prices by who was shopping.
“We price the product, not the person,” Furner said.
The questions were not idle. Walmart has been rolling the labels out across its roughly 4,600 U.S. stores, and the sight of prices that can change without a human touching a shelf touched a nerve in a country already wary of algorithmic pricing. Social media speculation that the tags, combined with the retailer’s AI tools, would enable individualized pricing spread quickly enough that the company felt compelled to answer it in writing.
The promise matters because the capability now exists. Digital shelf labels can be changed from a central system in seconds, and Walmart’s AI assistant, called Sparky, sits in front of customers who volunteer plenty of personal information while they shop. The technical ability to turn that data into an individualized price is real, and retailers have been experimenting with it.
Furner’s answer was to rule it out. “When you engage with Sparky, that’s an invitation to serve you better, not to use your personal information to set a personalized price,” he wrote.
Sparky is Walmart’s attempt to put AI in front of shoppers as a companion that helps them find products, compare options and answer questions. It is precisely the kind of tool that, in other retailers’ hands, could learn enough about a customer to set a price. Furner’s letter is, in effect, a promise about what Walmart will not do with the data such a tool collects.
He tied the pledge to a principle Walmart has leaned on for more than half a century: Every Day Low Prices. The strategy dates to the company’s founder, Sam Walton, who opened the first Walmart in Rogers, Arkansas, in 1962 and built the retailer on the idea that customers should not have to hunt for sales.
Every Day Low Prices was always more than a slogan. In the discounting era, most rivals ran on promotional pricing — high everyday prices punctuated by sales. Walton’s bet was that steady low prices would win trust and volume, and the formula carried the company to the top of global retail.
Furner’s letter updated the promise for the age of the algorithm: a shopper should not have to guess whether Monday or Tuesday is the better day to shop, or wonder whether the person in the next aisle is getting a better deal.
The letter, which ran to roughly 600 words, laid out the rule in plain terms. Walmart would not vary prices based on a customer’s identity, income or purchase history, and would not charge different prices at different times of day. The digital shelf labels, Furner said, exist for a narrower purpose: to make sure the price on the shelf matches the price at checkout, and to spare employees the work of replacing thousands of paper tags by hand.
The labels are spreading fast. Walmart has said it aims to have them in every store and Sam’s Club location by the end of the year, a rollout that put the technology in front of millions of shoppers and, inevitably, produced the questions Furner was answering.
Analysts said the letter is as much about competition as about principle. As rivals experiment with dynamic pricing, Walmart is betting that a flat, predictable price is a selling point in its own right — a way to distinguish itself in a market where the tools for personalization are now cheap and widely available.
The stance also puts Walmart on one side of a debate that has reached regulators. The Federal Trade Commission has opened an inquiry into what it calls “surveillance pricing,” the practice of using AI and personal data to set individualized prices, and consumer advocates have argued that such pricing could quietly extract more from shoppers who can afford to pay.
Furner cast the commitment in a single line that has become the headline: the same item, the same price. It is a simple promise, and an unusual one in an industry that is just learning how much its new tools can measure.
Whether Walmart can hold to it as those tools improve is an open question. The company said employees will keep overseeing pricing and that it will keep testing its technology to make sure it complies with the commitment.
For now, the retailer has chosen to treat the ability to personalize prices not as an advantage to exploit, but as a line not to cross.
