Maryland bans personalized pricing in groceries, first in the U.S.

Maryland becomes the first U.S. state to prohibit retailers and third-party services from using personal data to set higher prices in grocery stores. Gov. Wes Moore signed the law, which includes exemptions for loyalty programs and promotions and has critics warning of weak enforcement and loopholes. If successful, it could spur similar bills in other states, while federal action on surveillance pricing remains limited.
