Targeted at large grocery and general merchandise chains with annual global revenue exceeding $1 billion – including retail giants Walmart, Kroger, Target and Amazon Fresh – the legislation prohibits retailers from using personal consumer data collected via surveillance tools to set individualized prices for the same goods, at the same time, for customers in the same geographic area. Surveillance pricing, also called algorithmic personalized pricing, relies on real-time data harvesting of shoppers’ browsing history, location tracking, past purchase records, demographic information, and even device type to adjust prices dynamically, often without customers’ knowledge. A 2023 investigation by Consumer Reports found that major grocery chains used this practice to raise prices on staple goods including eggs, milk and bread by up to 17% during peak shopping hours, or charge customers who regularly purchase higher-priced goods up to 25% more for the same items than infrequent shoppers. In one documented case, a Walmart customer in Silver Spring, Maryland found the same 50-ounce bottle of laundry detergent priced at $12.99 when logged into their Walmart account, versus $9.97 when browsing in incognito mode, a $3.02 difference tied directly to their past purchase history of premium cleaning products. Under the new Maryland law, retailers that violate the ban will face civil penalties of up to $1,000 per individual violation, plus restitution for affected customers, and the state attorney general’s office will be authorized to launch class-action lawsuits against chains that engage in widespread violations. Supporters of the bill argue that it fills a critical gap in consumer protection, particularly for low-income households that spend a larger share of their income on groceries and essential goods, and are disproportionately targeted by algorithmic pricing tools that detect limited access to alternative shopping options. For consumers across the U.S. looking to avoid falling victim to surveillance pricing before similar regulations are passed in other states, consumer advocates recommend several key steps: use incognito or private browsing mode when shopping online to avoid being tracked, clear browser cookies and cache regularly before checking prices, avoid logging into retailer accounts when comparing prices, use cross-platform price comparison tools such as Honey or CamelCamelCamel to verify historical price trends for items, and shop at local independent grocery stores that do not use algorithmic pricing tools. Opponents of the Maryland bill, including the Retail Industry Leaders Association, argue that the ban will restrict retailers’ ability to adjust prices in response to supply chain disruptions and competitive pressure, and could lead to higher overall prices for all consumers. But state lawmakers backing the bill note that the legislation does not ban temporary sales, location-specific pricing tied to operational costs, or loyalty program discounts that are offered equally to all members, only pricing that is adjusted based on individual consumer surveillance data.
