For millions of shoppers, grocery prices already feel unpredictable. Now, a new legal fight is forming around a bigger question: should stores be allowed to use personal data to decide what one customer pays compared with another?
Maryland has become the first state in the country to move directly against “surveillance pricing” in grocery stores. Governor Wes Moore signed the Protection From Predatory Pricing Act on April 28, 2026, framing the law as a way to protect families from data-driven price hikes at a time when food costs remain a major household concern.
The law targets a practice that many shoppers may not even realize exists. In simple terms, surveillance pricing means a company uses information about a person, such as location, browsing history, shopping habits, device activity, or demographic data, to estimate how much that person may be willing to pay.
That could mean two people looking at the same grocery item may eventually see different prices, not because the product changed, but because an algorithm made a prediction about them.
Maryland’s new law focuses on grocery stores and third-party grocery delivery services. According to the governor’s office, the measure bars grocers and delivery platforms from using dynamic pricing or a shopper’s personal data to set higher prices, aiming to make sure consumers pay a clear and consistent price at the register.
The law is expected to take effect on October 1, 2026. That gives retailers time to review pricing systems, digital shelf labels, loyalty programs, delivery app pricing, and any technology that may change prices based on personal data.
The timing matters because grocery shopping is becoming more digital, even inside physical stores. More retailers are using electronic shelf labels, online ordering systems, loyalty apps, and automated pricing tools. These systems can make price updates faster, but they also raise concerns about whether prices are becoming less transparent.
The Federal Trade Commission has already studied surveillance pricing and warned that companies may use detailed personal information, including precise location and browser history, to target consumers with individualized prices for the same goods or services.
For everyday shoppers, the legal concern is not just technology. It is fairness.
If a store uses broad discounts, weekly sales, or normal supply-and-demand pricing, customers can usually see what is happening. But if a price changes because of data collected about a specific shopper, the customer may never know why the bill went up.
That is why consumer advocates have been pushing lawmakers to act. They argue that personalized pricing could hit people hardest when they have fewer choices, such as parents buying baby formula, seniors ordering groceries online, or families living in areas with limited store competition.
Maryland’s law may also influence other states. Kiplinger reported that at least a dozen states have been considering legislation around dynamic or algorithmic pricing, while New York has already moved on algorithmic pricing disclosure rules.
Still, the Maryland law is not without criticism.
Consumer Reports warned that the law may contain loopholes, including exemptions connected to loyalty programs. Another concern is enforcement. Reports indicate that consumers may not be able to directly sue businesses under the law, with enforcement mainly left to the Maryland attorney general.
That means the practical effect may depend on how aggressively regulators investigate complaints and how clearly businesses are required to explain their pricing systems.
For consumers, the law is a sign that grocery pricing could become a bigger legal issue across the country. Shoppers may start paying closer attention to whether online prices match in-store prices, whether delivery app prices differ from shelf prices, and whether loyalty programs are giving real discounts or simply collecting more data.
For retailers, the message is also clear: pricing technology is no longer just a business decision. It is becoming a legal and consumer protection issue.
A store may still be able to offer sales, coupons, loyalty rewards, and promotions. But when pricing depends on hidden data about a shopper, lawmakers are beginning to ask whether that crosses a line.
This matters because groceries are not luxury purchases. Food is an essential household expense. When pricing systems become too personal, too opaque, or too difficult to challenge, consumers may lose trust in the basic idea that the price on the shelf is the price everyone can rely on.
The broader legal trend is likely to grow. Privacy, artificial intelligence, consumer protection, and pricing transparency are now overlapping in ways that directly affect household budgets. What started as a debate about online ads and digital tracking is moving into grocery aisles, checkout counters, and delivery apps.
Maryland’s law may be the first of its kind, but it probably will not be the last.
If you’re affected by this change, speaking with a qualified lawyer can help.
