A system designed to extract maximum profit from each transaction
In a quiet but consequential act of governance, Maryland has drawn a line between commerce and surveillance, becoming the first state to prohibit grocery retailers from using personal data to charge different customers different prices for identical goods. The law, HB 895, arrives at a moment when algorithmic systems have grown sophisticated enough to treat price itself as a variable — not a reflection of a product's value, but of a buyer's perceived willingness to pay. At its core, this is a question as old as markets: whether the exchange of essential goods should be governed by fairness or by the full extraction of what each person can bear.
- Retailers already possess the technology to charge two neighbors different prices for the same carton of milk, based on what algorithms have quietly learned about their spending lives.
- The practice has spread through loyalty programs, credit card data, and digital footprints — systems consumers joined for discounts, not knowing they were also submitting to financial profiling.
- Maryland lawmakers drew a sharp distinction between food and other consumer goods, arguing that dynamic pricing acceptable in airline seats becomes something different when applied to bread and milk.
- HB 895 does not dismantle loyalty programs or ban promotions — it specifically forbids using the data those programs collect to charge some customers more than others for the same product.
- Other states are watching closely, and the grocery industry is preparing to argue that restrictions will raise baseline prices — a debate that is only beginning to take shape nationally.
Maryland has become the first state in the country to ban surveillance pricing in grocery stores, signing into law HB 895 — a direct response to the growing practice of using personal data to charge individual customers different amounts for identical products.
The concern is both simple and unsettling. Two shoppers can stand in the same aisle, reach for the same item, and pay different prices — not because of a coupon or a sale, but because an algorithm has calculated what each of them is likely to accept based on their purchase history, loyalty card data, and digital behavior. Retailers have the technology to do this now, and some have already experimented with it.
What distinguishes groceries from airline tickets or hotel rooms — where dynamic pricing has become normalized — is that food is essential. Every household must buy it. The notion that a family's financial profile could quietly determine what they pay for basic nutrition struck Maryland's lawmakers as a line that should not be crossed.
The law is carefully drawn. It does not eliminate loyalty programs or prohibit promotions. It forbids retailers from using the data those programs collect to identify customers as high-willingness-to-pay individuals and charge them more. A store may still offer a discount to anyone with a loyalty card; it may not use that card to quietly raise prices for those it has profiled as able to afford more.
For years, the grocery industry has framed personalized pricing as a natural evolution of retail. Maryland's legislature saw it differently — as the automation of financial discrimination. Whether other states follow, and whether the law survives industry legal challenges, remains to be seen. For now, Maryland stands as the first to decide that some uses of data, however profitable, do not belong in the places where families feed themselves.
Maryland has become the first state in the nation to prohibit grocery stores from using surveillance data to charge different prices to different customers. The legislation, known as HB 895, represents a direct response to the growing practice of algorithmic pricing—a system in which retailers track individual shopping habits, purchase history, and personal data to determine what each customer will pay for the same item.
The concern driving the law is straightforward but unsettling. Imagine two people buying identical milk at the same store on the same day, but one pays $3.99 and the other pays $4.49, based on what a computer algorithm has learned about their spending patterns and willingness to pay. This is not hypothetical. Retailers have the technology to implement such pricing now, and some have experimented with it. The practice is legal in most of the country, which is why Maryland's move carries weight.
Surveillance pricing works by aggregating data from loyalty programs, credit card transactions, browsing history, and other digital footprints. Algorithms then calculate the maximum price each individual customer is likely to accept. Wealthier customers, or those with histories of buying premium products, might be shown higher prices. Customers on tight budgets, identified through their purchasing patterns, might see lower ones. The system is designed to extract maximum profit from each transaction, treating price not as a fixed value but as a variable tailored to the individual.
What makes this particularly troubling in the grocery context is that food is not a luxury good. It is essential. Unlike choosing between airline tickets or hotel rooms—where dynamic pricing is already commonplace and somewhat accepted—groceries are something every household must buy. The idea that a family's financial circumstances could determine what they pay for basic nutrition struck lawmakers and consumer advocates as crossing a line.
HB 895 explicitly forbids Maryland grocers from using personal data to set individualized prices. The law does not prevent stores from offering discounts or running promotions. It does not ban loyalty programs. What it does is prevent retailers from weaponizing the data those programs collect to charge some customers more than others for identical products. The distinction matters: a store can still offer a sale to anyone who signs up for a loyalty card, but it cannot use that card to identify you as someone willing to pay premium prices and charge you accordingly.
The passage of this legislation signals a shift in how at least one state views the relationship between data collection and consumer protection. For years, the grocery industry has argued that personalized pricing is simply an extension of existing retail practices—that stores have always charged different prices in different locations, or offered different deals to different customers. But Maryland's lawmakers saw something different: a system that could systematize and automate discrimination based on financial vulnerability.
Other states are watching. Consumer advocates and legislators in several other jurisdictions have begun discussing similar restrictions. If Maryland's law survives legal challenge and proves workable in practice, it could establish a template for a broader national movement. The grocery industry will likely resist, arguing that personalized pricing allows them to compete more effectively and that restrictions will ultimately harm consumers through higher baseline prices. That debate is just beginning. For now, Maryland stands alone—the first state to decide that some forms of data use, no matter how profitable, should not be allowed in the aisles where families buy their food.

So Maryland is saying grocers can't use data to charge different prices. But don't stores already do this with coupons and loyalty discounts?
They do, and that's the crucial distinction. A coupon or loyalty discount is transparent—you know the deal exists and you can choose to participate. What surveillance pricing does is invisible. The algorithm sees you, calculates what you'll pay, and shows you a price tailored to you alone. Your neighbor sees something different for the same milk.
But couldn't a store argue that's just smart business? Airlines do it all the time.
They do, and that's partly why this matters. Groceries aren't flights. You can't skip buying food. You can't comparison shop easily when prices are personalized. There's an asymmetry of power that feels different when it's about survival rather than leisure.
What happens if a store breaks the law?
That's still being worked out. The law exists now, but enforcement mechanisms and penalties will shape whether it's actually effective or just symbolic.
Will other states follow?
Almost certainly some will. This opens a conversation about what data use is acceptable when it touches essential goods. Once one state draws that line, others start asking why they shouldn't too.
