Amazon does not currently provide Buy Box % (Featured Offer %) metrics for used items, including used books.
You can view Buy Box performance data in Seller Central, but this is typically limited to:
New condition offers
Specific reports like Business Reports or Pricing Health
What this means for used sellers
There is no direct Buy Box % metric available for used listings
You’ll need to monitor performance indirectly by:
Checking your listings manually
Using repricing tools or third-party software
Tracking sales and pricing competitiveness
Quick Summary
