Error 100509 — Pricing policy violation

Your price violates Amazon's Marketplace Fair Pricing Policy — typically by being significantly above the price elsewhere or by using deceptive pricing tactics.

Amazon's Fair Pricing Policy prohibits significantly above-MSRP pricing, fake reference prices, and deceptive discount displays. Violations can result in Buy Box loss or listing suppression.

1. Review Amazon's Marketplace Fair Pricing Policy in Seller Central → Help → Policies.
2. Adjust prices to be in line with MSRP and other marketplace prices.
3. Don't set list_price artificially high to make sale_price look like a bigger discount.
4. If you genuinely believe pricing is correct, file an appeal with documentation.

• Pricing 30%+ above other Amazon sellers — Buy Box loss
• Setting fake high MSRPs to inflate apparent discount
