Amazon recently launched a new feature called #AmazonCart where Twitter users can add items to their Amazon shopping cart simply by tweeting that hashtag along with a product link.
If you’re scrolling through Twitter and see someone Tweet out an Amazon link to something you might want to purchase, like one of Matt Cutts’ occasional book recommendations, you can reply to that tweet with the hashtag #AmazonCart and automatically add that product to your shopping cart.
In order for this feature to work, you will need to connect your Twitter account to Amazon, which can be done by visiting the Social Settings section. If your Twitter account isn’t connected, you’ll receive a reply asking you to connect your account the first time you use the #AmazonCart hashtag.
Once the item is added to your card, @MyAmazon will send you a reply to confirm. If you live in the U.K. you can use this feature with the hashtag #AmazonBasket.
Also note that you can safely use the #AmazonCart hashtag without making a purchase, it will only save an item to your cart. You will still have to go to the Amazon website to complete the purchase, or if you decide you don’t want the item you can always remove it from your cart.
