Buy box
The buy box is the block on a product page where a marketplace shows one offer from one seller, with "Buy" and "Add to cart" buttons, when several sellers sell the same product. Whoever gets into the buy box receives most of the orders for that listing.
Plain explanation
On Amazon, dozens of sellers can sell the same listing. The customer sees not a list but one "chosen" offer. Amazon now calls this the Featured Offer (formerly the Buy Box): the offer in the block near the top of the page, with other sellers lower down in the "Other sellers on Amazon" list (Amazon).
Amazon does not publish the share of sales that goes through the buy box, so there are no numbers here: the ones circulating on blogs have no primary source.
What affects the choice
According to Amazon's official explanation, the most competitive offers get into the buy box. These are considered:
- Price: usually at or below the cheapest alternatives, shipping included.
- Delivery: fast and free, with a narrower date range. Amazon writes that fulfilling orders yourself can be as effective as FBA.
- Order quality: the right, undamaged, genuine item in the stated condition, with no payment disputes.
- Availability: a product that isn't in stock doesn't get into the buy box (Amazon).
Reasons for missing out: no stock, a price that is too high or too low. If a price looks like a mistake, the offer may be temporarily excluded until the seller confirms it (Amazon). Amazon does not reveal the full algorithm.
And in Ukraine?
The term came from Amazon. Rozetka's and Prom's public help pages contain no description of a "buy box" mechanic, so whether they use a similar mechanism is unknown. The principle is the same for any marketplace where several sellers share one listing: price, delivery speed, availability and service quality.
What a seller should do (practice)
- Work out your unit economics before cutting the price: "winning" the buy box at a loss makes no sense.
- Keep stock: a product that isn't there doesn't sell.
- Shorten dispatch time. Choose the fulfillment scheme (see FBO and FBS) with speed in mind.
- Watch complaints, returns and whether the description matches the product.
Common mistakes
- Price dumping without calculating margin.
- Automatic repricing with no lower limit.
- Sharp price jumps upward: the offer may drop out as uncompetitive.
- Ignoring account quality metrics.

Product feed
A product feed is a file or data stream with the full list of your products (name, price, availability, photo, link) that a store passes to Google, marketplaces and price comparison sites so they can show and sell its products.
