San Francisco (CNN Business) For the past eleven years, AceBeach has been selling hard-to-find electronics online. At one point, Apple products made up half of AceBeach's business, but in recent years Apple has made it increasingly difficult for third-parties to sell used or new iPhones, iPads and Apple Watches.

A new deal between Apple and Amazon is about to make it even harder. It could be the final blow for many small online resale and repair shops.

Amazon and Apple have stuck an agreement that lets Amazon list the newest Apple and Beats products when they come out, like the iPhone XS and XR. In exchange, Amazon will remove any non-authorized third-party sellers selling Apple products from the platform. The deal will begin later this year and apply to Amazon sales in the United States, United Kingdom, Japan, India, France, Germany and Spain.

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.
