# Buy Box Checker

> Location-level Amazon Buy Box monitoring built by Ad Badger. Buy Box Checker tracks Buy Box (Featured Offer) ownership across cities and postcodes on amazon.com, amazon.co.uk, amazon.ca, amazon.ie, and amazon.it, then reports losses, suspected hijackers, and regional suppression that Seller Central hides.

Buy Box Checker solves a specific gap: Amazon assigns Buy Box winners by delivery geography, so the seller winning the Featured Offer in Seattle may be losing it in Miami. National-level tools, including Amazon's own Seller Central dashboard, show only a single blended percentage. Buy Box Checker monitors each ASIN across a configurable set of locations and reports what changed in a once-daily briefing.

Key facts:
- The Amazon Buy Box (now officially the "Featured Offer") is the default "Add to Cart" purchase option; the vast majority of Amazon sales flow through it.
- The Buy Box winner can differ by location because delivery speed and inventory proximity are primary ranking factors. Measured across Buy Box Checker's own tracked products, as of August 15, 2026: 45.4% of tracked products currently have at least one location where the Buy Box is lost or suppressed (a point-in-time figure, not a window). Separately, on any given day, 20.6% of products checked in two or more locations showed a different Buy Box status across those locations that same day (mean of 18 complete days ending August 15, 2026; daily range 16.2% to 23.3%). The two figures have different bases and are not restatements of one another.
- Buy Box suppression happens when Amazon features no offer at all (a "See All Buying Options" button), often triggered by external price competition or price spikes.
- Buy Box Checker requires no Amazon Seller Central connection or API access. It checks public product pages, so any ASIN can be monitored, including a competitor's.
- **Checks run once every 24 hours** per ASIN per location, on every plan. Buy Box Checker does not offer real-time or event-triggered monitoring.
- **Alerts are delivered as one daily briefing** at an hour the user chooses, by email and optionally Slack, Google Chat, Discord, or any webhook endpoint. They are not instant. The Free plan receives no outbound alerts at all; free users see alerts in the dashboard when they log in.
- The unit of usage is an ASIN check: one product in one location. Plan limits meter ASINs multiplied by locations, so 100 ASINs in 10 cities is 1,000 checks.
- Plans range from a free tier (20 ASIN checks, 2 locations) to paid tiers up to 2,500 checks with unlimited locations. Marketplaces other than amazon.com require a paid plan.
- Buy Box Checker is a product of Ad Badger Inc. (adbadger.com), a company focused on helping Amazon sellers win.
