Amazon has made shopping even easier. Suppose a friend or acquaintance mentions an product on Twitter. If it’s an Amazon product, and you want to buy it, instead of clicking on it and then adding to your cart, you can hit reply and add #AmazonCart and it will automatically add it to your cart. It will not automatically purchase it so you don’t have to worry about impulse purchases. You need to connect your Amazon account to your Twitter account in Social settings in Twitter.
