Amazon, Twitter Link Up for Easy Shopping Through #AmazonCart

Amazon.com unveiled a partnership with Twitter on Monday that may signal the future of shopping lies in your social media feed. Starting today, Twitter users can link their accounts to an Amazon account, and automatically add items to the shopping cart by responding to any tweet with an Amazon product link with the hashtag #AmazonCart. Users never leave the Twitter feed, and the product is waiting for them when they head over to Amazon. It's potentially a new business model for Twitter, which so far has relied on sponsored tweets for revenue.
