It's been about a year since Twitter launched tests of e-commerce, and now it's rolling out a "buy now" button system wide—so any U.S. retailer big or small can sell physical products, digital goods or services all within a tweet.
Twitter says this puts it on its way being the world's biggest social marketplace. Twitter is looking to make it easy for a wide range of retailers to come on board by integrating with all the major e-commerce platforms: Shopify, Bigcommerce and Demandware. Merchants can also list their products on Stripe Relay to share and sell products. (One big retailer that's on board is Best Buy, which will be selling its products on Twitter through Stripe.)
