When you list products on Amazon, all customers browsing the site can find and purchase them (as long as the items can be delivered to the customer’s delivery address). Customers can add products to their shopping baskets using one of the following three methods:
Amazon selects the Buy Box winners from the pool of eligible sellers based on, among other things, price, availability and the customer’s delivery address. Buyers see the featured offer as the first choice while using the Add to Basket button on the product detail page. The Buy Box also features additional offers.
In addition to the Buy Box winning offers, up to three additional Buy Box eligible offers will be displayed in the More Buying Choices box on the product detail page. Any remaining seller offers (including offers that are not Buy Box eligible) are available at the bottom of the More Buying Choices box. Customers can click the new & used link (or new link) to go to the offer listing page.
