Seattle banned the grocery store from charging you a different price than the person behind you

“The future of shopping is two people holding the same milk, paying two prices, because one of them talked to a chatbot.”

The Story

Seattle City Council voted 7–2 to ban grocery “surveillance pricing”: using personal data — browsing, location, inferred income, even chatbot conversations — to set a different price for the same carton of milk. First U.S. *city* ban; Consumer Reports has estimated algorithmic experiments can add ~$1,200/year. Goes to the mayor for signature.

Why It Matters

Money + institutions + identity. The supermarket as a ranking engine. Not a generic privacy rant: a specific vote, a 62-page shopper dossier in the background reporting, prices as a personal UI.

Evidence

City of Seattle, KIRO, Consumer Reports / HN discussion
