Maryland Bans Surveillance Pricing in Groceries

What's happening

Maryland Governor Wes Moore signed the Protection from Predatory Pricing Act, making Maryland the first state to ban surveillance pricing in grocery stores. The law, effective October 1, 2026, prohibits retailers and third-party delivery apps from using personal data to charge different customers different prices for identical products. Surveillance pricing relies on algorithms fed by shopping history, location data, browsing behavior, and profiles purchased from data brokers to calculate an individual's willingness to pay. Two shoppers buying the same item in the same store could be charged different amounts. The law requires shelf prices to remain steady for one full business day. Violations carry fines up to $10,000 for a first offense and $25,000 for repeat offenses. Consumer advocates at Consumer Reports noted that exemptions for loyalty, membership, and subscription programs create loopholes that could limit the law's real-world impact.

What the Text says

The Hebrew scriptures return again and again to the marketplace as a place where justice is tested.

Proverbs 11:1A false balance is an abomination to Yahweh, but accurate weights are his delight.

The "false balance" in ancient commerce was a scale rigged to favor the merchant. A seller kept two sets of stones: heavier ones for buying, lighter ones for selling. The customer saw a transaction. The merchant saw an advantage built on asymmetry of information.

Amos 8:5-65Saying, 'When will the new moon be gone, that we may sell grain? And the Sabbath, that we may market wheat, making the ephah small, and the shekel large, and dealing falsely with balances of deceit;6that we may buy the poor for silver, and the needy for a pair of shoes, and sell the sweepings with the wheat?'"

Amos confronted merchants who adjusted their scales to exploit the vulnerable. The prophet did not appeal to their conscience. He named the structure itself as corrupt. The problem was not a dishonest individual but a system designed to extract more from those who knew less.

Surveillance pricing operates on the same asymmetry. The algorithm functions as an invisible scale, recalibrated for each customer based on data the customer never agreed to share and cannot see. One shopper pays $4.29 for eggs. Another pays $5.19. The shelf displays no price at all, only a screen that reads a profile.

Leviticus 19:35-3635"'You shall do no unrighteousness in judgment, in measures of length, of weight, or of quantity.36You shall have just balances, just weights, a just ephah, and a just hin. I am Yahweh your God, who brought you out of the land of Egypt.

Torah did not trust goodwill to protect fairness. It mandated standard weights. Maryland's law follows this ancient logic: build the protection into the structure.

The reflection

A posted price is a kind of promise. It says the cost of bread does not depend on who you are, where you live, or what an algorithm infers about your willingness to pay. When the price shifts with the customer, the marketplace stops being a place of exchange and becomes a place of extraction. The question is no longer what something costs. It is what someone can be made to pay.
