See who wins the Amazon Buy Box across multiple zip codes in one panel. Track geographic coverage for any ASIN. BuyBox Zones is a simple tool for Amazon sellers: on any Amazon product page, see who currently wins the Buy Box across every zip code you care about — all in one panel, without leaving the product page. Works for FBA and FBM sellers. Why it matters The Amazon Buy Box is geographic. The same ASIN at the same price can show one seller in Florida, a different seller in California, and a third in New York. If you don't know where you're winning and where you're losing, you're flying blind on your most important demand driver. What it does • Scans the Buy Box across 8+ zip codes in about 10–15 seconds • Shows the winning seller, price, delivery promise, and FBA/FBM status for each zone • Shows your own offer's price and delivery promise on every losing zone — so you can spot price gaps or delivery-promise gaps vs the winner • Colors zones green (you win) or red (you lose) against your configured seller name • Named zip-code templates (e.g. "Coastal cities", "West Coast only") — swap the active set with one click • Per-ASIN zone overrides for products shipping from different warehouses • Position the panel under the product title or above the Buy Box — your choice How it works Uses your own Amazon session — no proxies, no scraping infrastructure, no separate login. The extension sets Amazon's delivery-zip cookie via the same AJAX endpoint Amazon's own "Deliver to" dropdown uses, fetches the product page and the All Offers panel, and parses the structured offer data directly. Your original zip is restored after every scan. Privacy Runs entirely in your browser. The only network call outside amazon.com is a license check against our server (once every 24 hours). No analytics, no telemetry, no tracking. Your Amazon data never leaves your browser. Access Access is license-key gated. If you don't have a key, click "Request one" inside the extension Options — you'll get a reply within one business day. Not affiliated with, endorsed by, or sponsored by Amazon.com, Inc.
