According to the law firm Hagens Berman, which has filed a class-action antitrust case, Apple and Amazon have benefited hugely from the agreement while consumers have been paying higher prices.Following the start of the retail agreement in January 2019, Amazon became much more likely to get placement in the “buy box,” increasing its revenue from Apple devices.Italian regulators slapped Amazon with a fine last year for a similar deal involving Apple’s Beats audio products, reports Ars Technica.The firm was involved in numerous legal actions against Apple over the years, including the ebook price-fixing case and a battle over touchscreen patents.The law firm is asking anyone who purchased an Apple product via the Amazon buy box in 2019 or later to join the class action."
