Maryland Becomes First State to Ban Surveillance Pricing in Grocery Stores: What It Means for Your Wallet

You’re standing in the cereal aisle, scanning the shelves after a long day. Your app says a box of Cheerios costs $6.29. You sigh, grab it, and keep moving.

But your neighbor, standing at the exact same aisle, at the exact same time, glances at their phone and sees the exact same box priced at $4.99.

Why? Because an algorithm, somewhere in the digital ether, has quietly decided that you, based on your shopping history, your address, maybe even the type of phone you’re holding, are willing to pay more.

Sounds unfair? It is. And it’s called surveillance pricing.

Until now, there wasn’t much anyone could do about it. But on April 28, 2026, Maryland Governor Wes Moore picked up a pen and made history. With his signature, Maryland officially became the first state in the nation to ban surveillance pricing in grocery stores.

Let’s unpack what that really means, for your Saturday morning grocery run, for your budget, and for the future of how Americans buy food.

What Is Surveillance Pricing, Anyway?

Here’s the simple version.

Surveillance pricing — sometimes called personalized pricing, bespoke pricing, or algorithmic price discrimination, is the practice where companies take the personal data they’ve gathered about you and use it to set a price they think you, specifically, will pay.

We’re not just talking about your name or email address. The data can include:

• What you’ve searched for online
• Your location (sometimes down to your ZIP code)
• Your past purchases
• Your estimated income level
• Your family size
• Even how long your mouse hovers over an item on a screen

All of this gets fed into an algorithm that then spits out a price, a price that might be dramatically different from what the person next to you sees.

The Federal Trade Commission actually opened a formal investigation into this, and its initial findings were a little alarming. The FTC’s study confirmed that companies are consistently using detailed consumer data, from your precise location to your browser history, to target you with individualized pricing.

Surveillance Pricing vs. Dynamic Pricing: What’s the Difference?

Here’s where things get a little confusing, and that’s okay. A lot of news outlets have been throwing around the term “dynamic pricing,” and you might have heard it in connection with this new Maryland law. So let’s clear the air.

Dynamic pricing is the broader concept, it’s when a price changes based on general market forces. Think about Uber charging more during rush hour, or airline tickets spiking around Christmas. The price changes because demand is high, but everyone who books at that moment pays the same higher fare.

Surveillance pricing is the creepier cousin. Instead of changing the price based on overall demand, surveillance pricing changes the price based on you — your perceived willingness and ability to pay. As Consumer Reports policy analyst Grace Gedye puts it, “Surveillance pricing allows companies to take advantage of that information asymmetry and charge you as much as they think you’re individually willing to pay”.

All surveillance pricing is a form of dynamic pricing, but not all dynamic pricing is surveillance pricing. Maryland’s law is taking specific aim at the surveillance piece.

Real-World Examples: Instacart & Kroger Investigations

This isn’t just theoretical. It’s been happening.

A joint investigation by Consumer Reports, the Groundwork Collaborative, and More Perfect Union found that Instacart had been running AI-powered pricing experiments where shoppers were charged different prices for the exact same basket of goods, at the exact same time.

The findings were startling: some customers paid as much as 23% more than others for identical products. The investigation estimated that these algorithmic pricing practices could cost families up to $1,200 a year at checkout.

Separately, Consumer Reports dug into Kroger’s data collection practices and discovered the grocery giant was compiling intensely detailed shopper profiles, inferring customers’ likely income, education level, family size, gender, and even gauging their “loyalty” to the brand. One shopper who requested their personal data under state privacy law received a staggering 62-page profile.

This data, advocates say, is the engine that powers surveillance pricing. It gives stores the fuel they need to decide who pays more and who pays less.

How Maryland’s New Law Changes the Game

The newly signed legislation, officially called the Protection From Predatory Pricing Act (HB 895) , is the first law in the country to bluntly say: You can’t do this in grocery stores.

What the Protection From Predatory Pricing Act Actually Says

Here’s what the law does, in plain English:

• Ban on personalized pricing: Grocery stores (defined as food retailers of at least 15,000 square feet) and third-party delivery services like Instacart are prohibited from using a person’s individual data to charge them a higher price on the spot
• Prices must stay fixed: Stores are required to keep prices stable for at least one full business day. No more instant fluctuations based on time of day, weather, or what the algorithm thinks you’re willing to pay at 5:30 PM when you’re tired after work
• No targeting based on protected characteristics: The law specifically forbids using data tied to race, religion, or other protected class categories to shape pricing decisions

Enforcement, Penalties, and the Key Date: October 1, 2026

Here’s the timeline that matters most:

The law takes effect on October 1, 2026. Starting then, any grocery store or delivery service operating in Maryland that gets caught engaging in surveillance pricing will face:

• First offense: Fine of up to $10,000
• Subsequent offenses: Fine of up to $25,000

The Maryland Attorney General is responsible for enforcement. Notably, however, consumers cannot sue companies directly under this law, only the state can bring legal action, a detail that’s drawn sharp criticism from consumer advocates.

Why This Matters for Your Family’s Grocery Bill

At a time when families are already feeling squeezed by the high cost of everything, milk, eggs, bread, you name it, the idea that an algorithm might be quietly hiking the price on those same essentials feels like salt in the wound.

Governor Moore captured the sentiment at the bill signing: “At a time when technology can predict what we need, when we need it, when we’ll pay for it and also, when we’ll pay more for it, and at a time when we’re watching how big companies are then using these analytics against us to make record profits, Maryland is not just pushing back. Maryland is pushing forward because we are going to protect our people”.

The “Creepy” Tech Behind It: Digital Shelf Labels

Look closely the next time you’re in a Walmart or a Kroger. You might notice something different about the price tags.

A growing number of retailers are replacing old-school paper price stickers with electronic shelf labels, or ESLs — small, battery-powered digital screens attached to the shelf edge.

On their own, ESLs sound kind of handy. They let stores update prices quickly from a central system, ensuring the price on the shelf matches the price at checkout, and they free up employees from the tedious job of manually replacing tags.

But here’s the concern: When you combine ESLs with the vast ocean of data retailers already collect, through loyalty cards, apps, in-store cameras, Wi-Fi tracking, and purchase histories, you’ve built a system where a store can change prices, in the blink of an eye, for specific shoppers.

Walmart has committed to rolling out digital shelf labels to all its U.S. stores by the end of 2026. The United Food and Commercial Workers International Union (UFCW) has described ESLs as “the missing piece of the surveillance pricing puzzle”. Walmart, for its part, has stated it will not use the technology for dynamic or surge pricing, but the union remains skeptical.

The Maryland law takes aim at this broader ecosystem by requiring prices to remain stable for a full business day, effectively neutralizing the real-time adjustment capability that makes ESLs so potentially dangerous in the eyes of consumer advocates.

Could Other States Follow Maryland’s Lead?

Absolutely. And that’s part of what makes this law so significant.

About a dozen other states, including California, New York, Illinois, Colorado, New Jersey, and Massachusetts — have introduced bills that would similarly restrict surveillance pricing in food retail. A broader national campaign, led by the UFCW, is pushing for surveillance pricing bans and ESL moratoriums across the country, with legislative activity already surfacing in states like Minnesota, Georgia, and Iowa.

At the federal level, bills including the Stop Price Gouging in Grocery Stores Act have been introduced in both the House and Senate, aiming to prohibit retailers nationwide from using consumers’ personal data to set prices.

For now, Maryland is the clear pioneer. As one legal analysis noted, the state has launched “what could become a national test of whether lawmakers can meaningfully regulate a pricing system critics say is quietly spreading through the digital economy”.

The Loopholes: Why Critics Say the Law Falls Short

It’s important to keep this story honest and a little imperfect, because the law itself is imperfect.

While consumer advocacy groups like Consumer Reports praised Maryland for taking this first courageous step, they’ve been vocal that the final version of the bill was weakened by industry lobbying. Here are the major criticisms:

• Only bans charging higher prices. The law prohibits using personal data to set a price above a baseline, but it doesn’t establish what that baseline is. Critics argue this means a store could raise prices for everyone, then offer “individualized discounts” to some shoppers, arriving at the same discriminatory outcome through the back door.
• Exemptions for loyalty programs and subscriptions. Even if a loyalty program price is higher than the shelf price, it’s still allowed. Similarly, any pricing associated with a subscription service is exempted.
• Weak enforcement provisions. As noted, consumers don’t have the right to sue. Only the Maryland Attorney General can bring cases, and the law gives businesses a 45-day “cure period” before they face any consequences, a window critics call far too generous.

Tom McBrien, counsel at the Electronic Privacy Information Center, summed it up diplomatically: “We’re excited Maryland took this step but we do have serious concerns. The exemptions allow other ways of arriving at the same outcome that are just harder for consumers to detect”.

The UFCW went further, calling the law a failure and urging the legislature to go back to the drawing board next session to close the gaping loopholes.

Will Maryland lawmakers strengthen it? The 2027 legislative session will tell.

6 Ways to Protect Yourself From Surveillance Pricing Right Now

I know this all sounds kind of discouraging. The truth is, even with Maryland’s historic new law, surveillance pricing isn’t going to disappear overnight, especially if you live outside Maryland. But there are simple, practical steps you can take, starting today, to shield yourself from being profiled and overcharged:

1. Clear your cookies and cache regularly. Tracking data that companies use to build your profile lives in your browser. Deleting it frequently resets the picture and makes it harder for algorithms to target you.

2. Use a VPN, especially when grocery shopping online. A VPN masks your location, which is one of the key data points retailers use to determine what price to show you. If they don’t know where you are, they can’t peg you to an affluent ZIP code.

3. Be cautious with store loyalty programs and apps. Yes, those discounts are tempting. But remember: every loyalty card swipe is feeding data into the store’s profile on you. Consider whether the savings are worth it, or at least limit how many programs you’re enrolled in.

4. Shop around using different devices. Before making an online grocery purchase, check the price on both your phone and your laptop. Sometimes the prices are surprisingly different, and you can pick the lower one.

5. Avoid repeated searches for the same item. When retailers see you repeatedly looking for something, especially with urgency, they know you’re likely to buy and may raise the price accordingly. If you need to comparison shop, use different browsers or incognito mode.

6. Use guest checkout instead of logging in. When you check out as a guest, the retailer can’t tie your current shopping session to your long-term purchase history. It’s an easy way to slip under the radar and possibly see a lower price.

These aren’t perfect solutions. But together, they create enough friction to make it much harder for an algorithm to build an accurate, exploitable picture of you.

Maryland just drew a line in the sand, one that millions of grocery shoppers across the country will be watching.

The Protection From Predatory Pricing Act is genuinely historic. It’s the nation’s first explicit legal ban on using your personal data to secretly hike the cost of your cereal, your milk, your bread. For Maryland families, it promises a level of price transparency and consistency that simply hasn’t existed when electronic shelf labels can blink prices up and down at the speed of an algorithm.

But it’s also a first draft, one that critics say has too many escape hatches for the retail industry to wriggle through.

What happens next is the real story. Maryland lawmakers return to Annapolis for the next legislative session with pressure mounting to tighten the law. Other states, from California to Colorado, are now studying Maryland’s move as they consider their own bans. And at the federal level, there’s growing, though divided, momentum to take on surveillance pricing nationally.

For now, here’s what you can hold onto: The direction is finally shifting. The sensors watching you in the grocery aisle, the invisible data profiling you didn’t consent to, these practices are being pulled into the light. And whether you live in Baltimore or Boise, you have more power than you think to guard your wallet against them.
