Twitter is testing out for new feature called “Shop module” a shopping feature on Twitter by adding Buy Now button to the business’s profile where they can add product pages and product collections.

The Shop Module is a dedicated space at the top of a profile where businesses can showcase their products. When people visit a profile with the Shop Module enabled, they can scroll through the carousel of products and tap through on a single product to learn more and purchase — seamlessly in an in-app browser, without having to leave Twitter.

Twitter testing this Shop module with a small number of brands in the United States, people in the U.S. who use Twitter in English on iOS devices will be able to see the Shop Module.
