2. Make Sure You Win the Buy Box & Don’t Lose It
Amazon Buy Box is a section on the right-hand side of a product page that contains an "add to cart" button, which allows the product displayed in this box to be purchased with a single click.
The Buy Box placement will instantly increase your sales by up to 80%. Using an Amazon Repricer can help you get and stay in the Buy Box indefinitely.
To start seeing its benefits you should try to get it as soon as possible. Although Amazon's algorithm that defines which seller will occupy this position is complex, we already know a few things. You must choose Amazon FBA ("Fulfillment By Amazon"), a service that Amazon provides to sellers to store, ship and manage the returns of their products. Sellers therefore only have to worry about sending these products to Amazon.
Amazon gives preference to FBA sellers so you will have a better chance of getting the Buy Box if you are one of them.
If you run out of stock you will not be able to use the Buy Box. It's as simple as that. So make sure you don't run out of stock and don't let competitors take your position.
