Buy Box (Featured Offer)
Definition
The "Add to Cart" spot on an Amazon product page. When several sellers offer the same item, Amazon picks one to win it, and that seller gets most of the sales.
Want a deeper explanation?
For brands, losing the Buy Box usually means a reseller or price issue, and it shows up as a sudden sales drop with no change in demand.
Price, fulfillment method, stock levels and seller performance all factor in. Watch for: price cuts made to win the Buy Box back without checking contribution margin first.
Example
Three sellers list your ASIN. When a reseller undercuts your price by $1, they win the Buy Box and your daily sales drop from 60 units to 15.
