You can now fill your Amazon cart using Twitter.

According to USA Today, the online retailer launched the service Monday. It's called #AmazonCart which lets shoppers add items to their Amazon carts by using that hashtag.

When you see something on Twitter shared with an Amazon link, if you'd like to purchase that item, you just have to reply to that tweet with the hashtag #AmazonCart and it will automatically be added.

Amazon said it's all about convenience-- you don't have to switch apps or remember what you saw on Twitter in order to make purchases anymore.

To use the feature, you must make sure your Twitter and Amazon accounts are synced.
