>>Unlike eBay, where each vendor maintains a separate listings page, Amazon tidily groups its Marketplace sellers by item, hiding away the inferior offers, to showcase the best deals up front. (In seller parlance, landing the number-one spot is called "getting the buy box.") It's a key difference. For example we purchase shipping labels on Amazon and Ebay. On Amazon it's harder to know what you're getting unless you carefully check the marketplace seller you're buying from. The intuitive process of just reordering what worked for you previously from your purchase history doesn't work on Amazon as it does on Ebay. All too often, a different seller now owns the buy box with an inferior product.
