This isn’t the first time Amazon crack down on third-party sellers.

Amazon will sell and ship Apple products, which it will get directly from Apple. It will also list products from some approved Apple resellers.

Sellers found out about the change Friday morning in a letter from Amazon, obtained by CNN Business. They have until January 4, 2019 to sell their existing products before Amazon removes all of their listings. Amazon recommended they contact Apple if they’d like to become an authorized reseller and continue selling products on its site.

This isn’t the first time Amazon has worked with retailers to crack down on third-party sellers. When AceBeach was selling some popular toys, Amazon started requiring documentation from manufacturers like Hasbro giving permission to sell their products, said AceBeach’s owner.
A 2013 Supreme Court ruling upheld the right of people to resell any items they have purchased legally, even if they are copyrighted. But as a business, Amazon has full control over who can sell what on its platform.
Sometimes it uses that power against its biggest competitors. Amazon has blocked the sale of Google devices like the Chromecast that compete with its own smart speakers and streaming devices. And even with this new deal, Amazon still won’t sell Apple’s HomePod, a competitor to Amazon’s Echo devices.
