Amazon used an algorithm to essentially raise prices on other sites, the FTC says

The FTC reportedly alleges that Amazon used an algorithm to monitor prices on other websites, and then raise its own prices to match the highest prices it found. The practice is known as “dynamic pricing,” which is illegal if there is a collusive agreement or if Amazon had an unfair advantage over other retailers, the FTC has claimed. Amazon has denied the allegations and has said that it operates in full compliance with the law.
