Amazon has rolled out a new feature allowing Twitter users to select items for purchase on the online retail site without leaving the messaging platform.

The new feature called #AmazonCart allows people to link their Twitter and Amazon accounts for in-app purchases.

“We know that discovering products and services on Twitter is a natural, and we always look for ways to make that easier for users,” said Twitter spokesman Will Stickney in a statement on Monday.

“That’s why we built this capability through our relationship with Amazon.”

Terms of the deal were not announced.

Amazon made the announcement in a tweet, calling it “an exciting new way to add Amazon products to your cart, without leaving Twitter”.

The service is available for customers of Amazon in the United States and in Britain, where it is called #AmazonBasket.

Some reports pointed out a potential privacy issue: that because tweets are mostly public, the Amazon purchases would likely be visible on Twitter.
