Online retailers are constantly experimenting and iterating on connecting social media campaigns with more sales, and this is certainly true of Amazon.com's efforts with its automated add-to-cart hashtag, #AmazonCart. With the tagline "Add it Now, Buy it Later," Amazon has implemented a process whereby users who link their Twitter ID to their Amazon account can add products to their shopping cart from within Twitter simply by replying to any tweet including an Amazon link with the hashtag #AmazonCart. Amazon touts this as a convenient way for users to capture items seen while browsing Twitter for future reference. Retailers are supporting the effort by tweeting instructions and opportunities to use the hashtag from their own brand accounts.
