Buy Box Mapper - See Who Wins the Buy Box Across the US

Amazon’s Featured Offer (Buy Box) isn’t the same everywhere.

Buy Box Mapper lets sellers instantly check who owns the Buy Box across different US ZIP codes — helping you understand geographic Buy Box rotation, detect suppressed regions, and make smarter pricing and inventory decisions.

Perfect for:

Amazon FBA sellers

Wholesale sellers

Arbitrage sellers

Agencies and analysts

🔍 What It Does

Buy Box Mapper simulates delivery locations across the United States and shows which seller wins the Featured Offer in each region.

Instead of guessing why your Buy Box percentage fluctuates, you can now see it by geography.

Enter multiple ZIP codes and instantly see Buy Box winners per location.

📦 Multi-ASIN Scanning

Check several ASINs in one run to analyze:

Catalog Buy Box consistency

Buy Box Mapper - See Who Wins Amazon’s Buy Box Across the US 
Built by an Amazon seller, for Amazon sellers 🚀

This extension helps you see who wins Amazon’s Featured Offer (Buy Box) across different US ZIP codes for any ASIN. 

The winner of the Buy Box is not always the same everywhere. A product that wins the Featured Offer in one region may lose it in another. Buy Box Mapper gives sellers a geography-based view of Buy Box ownership so you can spot regional gaps, competitor wins, and inconsistent coverage that a single-location check can miss.

Use Buy Box Mapper to:
• Check Buy Box winners across different US ZIP codes
• See where your offer is winning, losing, or suppressed
• Understand geographic Buy Box variation
• Make smarter pricing, inventory, and replenishment decisions

This is especially useful for:
• Amazon FBA/FBM sellers
• Wholesale sellers
• Online arbitrage sellers
• Agencies and analysts

Instead of guessing why Buy Box share changes, see where it changes, and comprehend why. 

Whether you are researching an ASIN, tracking competitor presence, or troubleshooting lost Buy Box coverage, Buy Box Mapper gives you a faster and clearer way to understand Buy Box performance across the US.
