What is the Buy Box and how do you lose it?

On Amazon, several sellers may be offering the same product at the same time. All offers are grouped on a single product page, with only one prominent "Add to Cart" button. A lot of Amazon's alchemy goes into determining which offer is associated with that button. It makes its decision based on availability, price, seller reputation and more.

Brands which have a direct sourcing relationship with Amazon (Vendors) may think that they have the rightful claim to the Buy Box. In many instances, however, they will lose the buy box to third-party sellers.

Some of BlueBoard's clients, prominent international brands, have reported revenue losses of up to 40% over a quarter due to Lost Buy Box issues.

Lost Buy Box Amazon BenQ

Losing the Buy Box means that although Amazon has inventory from the manufacturer, it will favor linking the Add to Basket button to a 3rd-party seller. This can happen for a variety of reasons, but it usually means that the 3rd-party seller has a good track record and is offering a better price. Amazon explains on their vendor help site how the Buy Box is attributed.

In the example above, the price offered by the 3rd-party vendor is the same as Amazon's. Yet Amazon is not promoting its own inventory.

This causes a direct hit to the performance of the brand. Customers could be buying from them, but will instead get stock from a dubious source. In turn, Amazon may complain that their inventory is not selling fast enough. To maximize their sales, brands must satisfy 100% of the natural demand and reduce the rate of Lost Buy Box.

How to keep track of Lost Buy Box events?

Keeping track of lost buy boxes can be very tedious. Clients reported that manual lost buy box checks require 2 hours of work every day, for every Account Manager.

BlueBoard offers several ways to fast track this process: a dashboard, email notifications, data extracts, and an API.

  • Amazon Buy Box -  Sold in Direct but Lost: Amazon is Selling the item, but another seller has taken possession of the Buy Box. This column should be your primary focus!
  • Amazon Buy Box - Winner Name: Either Amazon or a marketplace seller depending on who won the Buy Box. Use it to spot frequent Buy Box thieves.
  • Amazon Buy Box - Price: the price offered by the winner of the Buy Box,
  • Amazon Buy Box - Is Winner Direct?: yes if Amazon won the Buy Box, no if it is a Marketplace seller,
  • Amazon Buy Box - Is Winner Lowest Mkt?: yes if the Buy Box was won by a marketplace seller AND this marketplace seller offered the lowest price of all. No in all other cases,
  • Amazon Buy Box - Someone Won?: no, if there is no Buy Box on the page (there may still be some marketplace seller, only Amazon did not deem them worthy of the Buy Box!).

Brands need to act on this monitoring to fix situations and increase performances.

  • Take action with Amazon, for example when a Lost Buy Box is due to an algorithm issue,
  • Document Lost Buy Box events to help in future negotiations with Amazon and to keep track of your progress,
