Walmart is putting digital price tags on every shelf in every store by the end of this year. They say it’s about efficiency — updating a price used to take two days with paper tags, now it takes minutes. What they’re not telling you is that the same technology lets them change the price of milk at 5pm when every tired parent in the zip code walks through the door. The grocery workers’ union has a name for it: surveillance pricing. Uber for your cereal aisle. The tags can respond to foot traffic, time of day, weather, local demand. The people who used to change those paper tags are, of course, being eliminated. The efficiency gain is you losing a coworker and paying more for eggs during a cold snap.
The UFCW is trying to get the technology banned in New York and a handful of other states. Walmart says the tags improve the “in-store experience.” The in-store experience of watching the price of ground beef tick upward while you stand there holding it. They already got $2.4 billion back in tariff refunds this summer. Now they want the ability to charge you more on Tuesday at 6pm than Wednesday at 10am for the same box of pasta, and no human has to approve the change or explain it to you at the register. The algorithm adjusts. The clerk who used to stick the paper tag on the shelf is gone.
