Now you can purchase products by Tweeting for them
American Express card holders can now purchase select products via Twitter. After syncing your Amex card to Twitter, tweet a specific product hashtag, AmexSync will send you a reply with a confirmation code, tweet that and you've made a purchase. For now, orders will come with free two-day shipping.
