Many items on Amazon come from third-party sellers on the Marketplace, indicated by a "Sold by" line near the "Add to Cart" button. If both Amazon and third-party sellers offer the item, the large "Add to Cart" button buys from Amazon, and you'll see a few alternative "Add to Cart" buttons with different prices and a link to a full list of used and new versions of the product. Marketplace sellers set their own prices, so you might find a great discount on a used item, or come across a rare, discontinued product that's only for sale at a collector's price. Even when buying from another seller, Amazon itself handles your payment, so you don't need to worry about your credit card information leaking out.
Throughout the store there are features like “Most-Wished-For,” a collection of products that are most added to Amazon.com Wish Lists; “Trending Around NYC,” hot products that NYC-area customers are buying on Amazon.com; “Frequently Bought Together”; and “Amazon Exclusives.” These features, along with customer review cards with quotes from actual customer reviews, make it fun and easy to shop.
Not only do these sellers enjoy increased favor with customers, but they also receive better placement on product pages and may qualify for Buy Box perks. By ‘winning’ the Buy Box, you will get default sales when a client clicks the “Add to Cart” button for your product. It’s important to note that only professional sellers qualify to be featured merchants.
