On May 5, 2014, Amazon unveiled a partnership with Twitter. Twitter users can link their accounts to an Amazon account and automatically add items to their shopping carts by responding to any tweet with an Amazon product link bearing the hashtag #AmazonCart. This allows customers to never leave their Twitter feed and the product is waiting for them when they go to the Amazon website.[146]

Amazon's home page provides three methods to start finding and buying items. The front page itself shows off featured items, and once the site starts learning your tastes, it will display products based on your history. To find a specific item, type in the search bar at the top of the page. Press "Enter" to search the entire catalog, or select from the drop-down menu set automatically to "All" to search a specific category, which also enables the "Refine" capability for more specific results. If you'd rather just window shop, click "Shop by Department," to pick a section to browse.

Use apps to check prices in real-time. “The app ShopSavvy is really useful when you’re out shopping in stores because you can scan the barcode on items and see if there is a better deal elsewhere,” says Palmer of Nerdwallet. Woroch is also a fan of ShopSavvy, as well as Flipp, which provides circulars all in one place so you can quickly compare to plan your shopping trip strategically.

Amazon employs a multi-level e-commerce strategy.

The company lets anyone sell nearly anything using its platform. In addition to an affiliate program that lets anyone post-Amazon links and earn a commission on click-through sales, there is now a program which lets those affiliates build entire websites based on Amazon's platform.[147]

Associates can access the Amazon catalog directly on their websites by using the Amazon Web Services (AWS) XML service. A new affiliate product, aStore, allows Associates to embed a subset of Amazon products within another website, or linked to another website. In June 2010, Amazon Seller Product Suggestions was launched (rumored to be internally called "Project Genesis") to provide more transparency to sellers by recommending specific products to third-party sellers to sell on Amazon. Products suggested are based on customers' browsing history.[133]
