Out of stock in Denver, fine in Austin. Same product, same day. Most Amazon sell

Out of stock in Denver, fine in Austin. Same product, same day.
Most Amazon sellers find out about a regional stockout days later, after conversion rate slips or the ad report looks off.
When we analyzed 598,231 Buy Box checks across 1,775 products and 116 delivery locations (https://lnkd.in/gmrw4D5N), three patterns stood out:
1. 26.2% of checks returned a stock warning:
Roughly 1 in 4 checks showed inventory trouble on the page shoppers actually see (20.3% low stock such as "Only 5 left in stock" and 5.9% completely out of stock).
2. 89.1% of stock warnings were city-specific:
When a listing hit a stock warning, nearly 9 times out of 10 it ran low or went out of stock in specific cities while staying in stock elsewhere on the exact same day.
3. Low stock hurts before zero does:
Across 30 days, 59.6% of tracked products hit a stock warning (53.2% dropped into low stock and 13.0% went fully out of stock at least once), often losing regional Buy Box share before national inventory ever hit zero.
So we built city-by-city stock tracking for your own products into Buy Box Checker across all six marketplaces (US, UK, Canada, Ireland, Italy, and Germany) on our paid plans:
-> Morning digest stock alerts: Out of stock, low stock (confirmed on a second daily check so a single odd reading never sends a false alarm), and back in stock, named by city with a per-product on/off switch.
-> Per-city stock strip & Stock Changes page: One colored square per day per location (showing in stock, low, out of stock, or when a competitor held the Buy Box instead of guessing your stock), filterable by brand, group, or ASIN.
-> AI connector access (buyboxchecker.com/mcp): Ask Claude or ChatGPT "Which of my products went out of stock last week, and where?" via the new list_stock_changes tool.
Have you ever traced a sudden Amazon PPC dip back to a regional FC transfer or city-level stockout?
