Maryland passed the Protection From Predatory Pricing Act this month, becoming the first state to ban 'surveillance pricing' — the practice of using personal data like browsing history or purchasing behavior to charge different customers different prices for the same item. The law applies to grocery stores and delivery services, with violations treated as deceptive trade practices carrying fines and lawsuits. Consumer Reports backed the move but flagged significant loopholes: the ban only blocks using personal data to charge *higher* prices without a baseline, and it exempts loyalty programs, memberships, and subscription services — meaning retailers can still deliver personalized pricing through these channels.
