Buy Box (Amazon)
The box on Amazon that displays 'Add to Cart.' The seller who wins the Buy Box gets 80-82% of sales on that ASIN. Other sellers appear under 'Other Sellers' — with almost no clicks.
In practice
The Buy Box is Amazon's prime real estate. A product listed on FBA, with a competitive price, high seller rating, and available inventory, wins the Buy Box. A seller who loses it loses sales.
Common misconception
'The lowest price always wins the Buy Box.' Not true. Amazon weighs price plus FBA/FMB status plus seller metrics plus shipping time. A single FBA seller can beat a cheaper FBM seller because Amazon favors Prime.
How to fix it
Lost the Buy Box? (1) Check price — did a competitor lower theirs? (2) check seller metrics — order defect rate, late shipments, (3) check inventory — being out of stock causes immediate loss, (4) consider an automatic repricer.
Example
An Amazon seller ran FBM with a price $3 lower than an FBA competitor and didn't win the Buy Box. Switching to FBA at the same price as the competitor won the Buy Box. Sales quadrupled in the first week.
