The FTC alleges that Amazon deters sellers from discounting goods and lowering prices below what is available on Amazon, pushing prices higher across the internet. It also argues that Amazon pushes sellers into its fulfillment services, making it more expensive for sellers to offer their goods elsewhere. California lodged similar complaints in a lawsuit filed just more than a year ago. Kahn declined to directly address whether she hoped the suit would lead to a breakup of Amazon into smaller companies, but she stressed that it showed Amazon had established an unfair advantage.
