Frequently Asked Questions

Why don't I have the Buy Box?
Top reasons: not Featured-Offer eligible (new account, < 90 days), price above competitor, FBM with poor delivery time, low seller rating, frequent stockouts.
Does FBA always win?
No, but it gets ~10–15% pricing slack. FBM with same-day shipping and 99%+ rating can match. Account age & order defect rate matter equally.
How fast does Buy Box rotate?
Hourly to daily. Amazon weights metrics over rolling 30-90 day windows. New positive metrics take time to register.
