Error 13066 — Not eligible for Buy Box

Listing is live but ineligible for the Buy Box. Loss of Buy Box typically drops sales by 80%+ on Amazon.

Buy Box eligibility requires Featured Merchant status — minimum order count, low cancellation rate, prime fulfillment offering, competitive pricing, low return rate.

1. Check Seller Central → Performance for which metric is failing.
2. Improve the underperforming metric: reduce cancellations, switch to FBA for prime eligibility, lower price.
3. New seller accounts typically gain Buy Box eligibility after 90 days of solid performance.
4. Maintain seller metrics in green zones.

• Pricing too high above competitors loses Buy Box even with great metrics
