马里兰州成为第一个禁止"监控定价"的州, 这种做法是零售商使用个人数据为同一商品设置不同的价格. Maryland has become the first state to ban "surveillance pricing," a practice where retailers use personal data to set different prices for the same item. 州长韦斯·摩尔承诺签署"保护不让人购买的价格法案", Governor Wes Moore has pledged to sign the Protection from Predatory Pricing Act, which prohibits adjusting grocery prices based on shopping habits, location, or income. 法律将于10月1日生效,要求至少一个工作天固定价格,尽管忠诚度计划和订阅服务的豁免仍然存在. The law takes effect October 1 and requires fixed prices for at least one business day, though exemptions for loyalty programs and subscription services remain.
