Maryland Moves to Ban Surveillance Pricing

When Grocery Prices Become Personal

When news broke that Maryland was set to become the first U.S. state to ban surveillance pricing in retail grocery stores, consumer advocates saw it as a major step in the fight against data-driven shopping manipulation. The new law, called the Protection from Predatory Pricing Act, targets a growing concern in modern retail: the possibility that stores could use personal data to charge different people different prices for the same item at the same time.

For shoppers already struggling with rising grocery bills, the idea feels unsettling. It suggests that the price on the shelf may no longer be just a price. It could become a calculation based on who you are, where you live, what you buy, how often you shop, and how much a company believes you are willing to pay.

What Surveillance Pricing Means

Surveillance pricing, sometimes called personalized pricing or dynamic pricing, happens when a business uses data about individual customers to adjust prices. This could include browsing habits, purchase history, location, income estimates, family size, dietary needs, or even how loyal a shopper appears to be.

Dynamic pricing is already common in many industries. Airlines change ticket prices constantly. Ride-sharing apps adjust fares based on demand. Online marketplaces often change prices based on timing, availability, and user behavior.

But grocery stores feel different to many consumers because food is essential. A higher price for milk, bread, eggs, or baby food can directly affect household budgets. That is why Maryland’s proposed law has drawn attention: it treats data-driven grocery pricing as a consumer protection issue, not just a business strategy.

Why Maryland Took Action

Governor Wes Moore said he plans to sign the bill into law after state lawmakers passed it. His argument is simple: at a time when families are already stretched by the cost of groceries, housing, and daily essentials, new retail technologies should not be used to increase pressure on working households.

The concern intensified as major retailers began adopting digital shelf labels. These electronic tags allow prices to change quickly without workers manually replacing paper labels. Supporters say they improve efficiency. Critics worry they could make it easier for stores to raise prices instantly, test different prices, or use predictive technology to charge more based on customer data.

Maryland’s bill seeks to stop large retailers from using personal information to set different prices in real time. However, it still allows promotional discounts and loyalty program benefits, which has become one of the most debated parts of the law.

The Power of Retail Data

Modern retailers know far more about shoppers than many people realize. Every app search, loyalty card scan, online order, coupon click, location ping, and product view can become part of a customer profile.

Consumer Reports warned that retailers may know whether a shopper lives near competitor stores, whether they often buy certain products, whether they have children, what dietary needs they may have, and what income level they appear to fit. In the hands of a retailer, that information can create a pricing advantage.

The fear is not only that companies know too much. The deeper concern is that shoppers do not know how that information is being used. If two people standing in the same store could be offered different prices based on hidden data profiles, the basic idea of fair pricing begins to break down.

What the Maryland Law Would Do

The Maryland act is designed to create clear limits for grocery retailers. Under the law, grocery stores must keep prices fixed for at least one business day, preventing rapid hourly price changes that could confuse or disadvantage shoppers.

The bill also prohibits retailers from using surveillance data to set different prices for different individuals. That includes data related to shopping habits, ethnicity, income, or other personal characteristics.

Violations would be treated as unfair or deceptive trade practices. Businesses could face fines of up to $10,000 for a first violation and up to $25,000 for later violations. The law is scheduled to take effect on October 1, 2026.

Why Consumer Groups Still Have Concerns

Although Consumer Reports supported the effort behind the bill, the group said the final version does not go far enough. One major concern is the exemption for loyalty and membership programs.

That exemption matters because loyalty programs are one of the main ways retailers collect customer data. If prices connected to loyalty programs can still change in ways that disadvantage shoppers, critics worry the law may leave open a major loophole.

Consumer advocates also criticized the enforcement structure. Under the bill, consumers cannot directly sue companies if they believe they were harmed by surveillance pricing. Only the Maryland Attorney General can bring legal action. In addition, companies receive notice and 45 days to fix violations before facing stronger consequences.

Retailers Push Back

Retail groups have opposed restrictions on dynamic pricing, arguing that pricing flexibility helps stores manage costs, offer promotions, and respond to market conditions. From their perspective, digital pricing tools can make operations more efficient and help retailers compete.

They also argue that loyalty programs often benefit customers by offering discounts and personalized deals. Many shoppers willingly sign up for these programs to save money, and retailers say banning or limiting them too aggressively could reduce consumer benefits.

But critics respond that there is a difference between offering a clear discount and using personal data to determine the highest price someone might tolerate. That distinction is at the center of the surveillance pricing debate.

The Instacart Example

Concerns about personalized grocery pricing grew after Consumer Reports investigated pricing practices on Instacart. The group had hundreds of consumers shop for the same basket of goods at the same time.

The investigation found that shoppers were shown different prices for the same products from the same stores. In some cases, price differences were reportedly as high as 23 percent for certain items. Consumer Reports estimated that such differences could cost families more than $1,200 per year.

After the investigation, Instacart said it would end the program that led different shoppers to see different grocery prices on its platform. The case became an important example of why consumer advocates want clearer rules before personalized pricing becomes more widespread.

Why This Could Spread Beyond Maryland

Maryland may be the first state to act, but it is unlikely to be the last. Other states, including California, Colorado, Illinois, New Jersey, and New York, are also considering restrictions on surveillance pricing.

If these states pass stronger versions of the law, retailers could face a growing patchwork of regulations. That could pressure national chains to adopt broader policies rather than managing different pricing rules in different states.

This is often how consumer protection trends begin in the United States. One state passes a first-of-its-kind law, others study the results, and the issue becomes part of a larger national debate.

What It Means for Shoppers

For shoppers, the Maryland bill is a warning about how retail is changing. Prices are no longer only shaped by supply, demand, labor, shipping, and competition. Increasingly, they may also be shaped by data and algorithms.

That means consumers may need to pay more attention to how they use loyalty cards, grocery apps, online shopping accounts, and location-based services. Convenience often comes with data collection, and that data may have financial consequences.

Still, the burden should not fall only on shoppers. Advocates argue that companies and regulators must create clear rules so consumers are not forced to guess whether they are being treated fairly.

A New Fight Over Fair Pricing

Maryland’s move to ban surveillance pricing marks a turning point in the relationship between shoppers, retailers, and personal data. It recognizes that pricing is no longer just a business decision. In the age of algorithms, it can become a privacy issue, a fairness issue, and a cost-of-living issue.

The law may not satisfy every consumer advocate, especially because of its exemptions and enforcement limits. But it sends a clear message that states are beginning to watch how retailers use technology at checkout.

As grocery stores become more digital, the biggest question may no longer be what an item costs. It may be why it costs that amount for one shopper and something different for another. Maryland’s law is an early attempt to answer that question before personalized pricing becomes the new normal.
