Twitter started testing a new feature – BUY button on their American site on 8th September 2014.
“Today we are beginning to test a new way for you to discover and buy products on Twitter. For a small percentage of U.S. users (that will grow over time), some Tweets from our test partners will feature a “Buy” button, letting you buy directly from the Tweet” – says official Twitter blog.
This is an early step in our building functionality into Twitter to make shopping from mobile devices convenient and easy, hopefully even fun. Users will get access to offers and merchandise they can’t get anywhere else and can act on them right in the Twitter apps for Android and iOS; sellers will gain a new way to turn the direct relationship they build with their followers into sales.
In Twitter’s test, an entire purchase can be completed in just a few taps. After tapping the “Buy” button, you will get additional product details and be prompted to enter your shipping and payment information. Once that’s entered and confirmed, your order information is sent to the merchant for delivery.
