Maryland's law prohibits retailers from using personal data to set individualized prices at checkout. The rule targets dynamic pricing tools like Amazon's cashierless technology and third-party analytics platforms that enable price discrimination at scale. Copycat bills in Colorado, California, Massachusetts, Illinois, and New Jersey suggest grocers have crossed a visibility threshold where algorithmic personalization in food retail now triggers state-level intervention, similar to how algorithmic hiring faced backlash in 2020\. The issue is less about privacy than fairness: consumers reject the idea that their purchase history, location data, or income level determines what they pay for milk. Grocery pricing is becoming the proving ground for broader restrictions on behavioral discrimination in commerce.
