- The Buy Box
- The 'Add to Cart' box on a product page that determines which seller's offer a shopper buys when multiple sellers list the same product.
Why the Buy Box matters
When more than one seller offers the same product, only one wins the Buy Box — the offer a shopper gets when they click 'Add to Cart'. The vast majority of Amazon sales go through it, so losing the Buy Box means losing the sale even though your offer is on the page.
What determines the Buy Box
Amazon weighs several factors, including:
- Fulfilment method — FBA and Prime-eligible offers are favoured.
- Price — landed price including shipping, relative to competitors.
- Seller performance — order defect rate, shipping speed and account health.
- Stock availability — you can't win it if you're out of stock.
For private-label brands that own their listing, the Buy Box is rarely contested — which is one more reason private label beats reselling. It becomes a live concern mainly on shared or wholesale listings.

Frequently asked questions
Why don't I have the Buy Box on my own listing?
Common causes are being out of stock, an uncompetitive landed price, a non-FBA fulfilment method, or account-health issues. If you're a brand-registered private-label seller and still losing it, check for hijackers on your listing and your account health dashboard first.
Does the Buy Box affect advertising?
Yes. Sponsored Products ads generally require you to hold the Buy Box to run, because the ad sends shoppers to the Buy Box offer. Losing it can stop your ads serving, which is why Buy Box stability underpins any PPC strategy.
