Gray Market / Diversion Source Finder

Finding an unauthorized listing is one thing — figuring out which distributor is actually leaking your product is another problem entirely. This extension keeps a simple record of which lot or batch codes went to which distributor, so when you spot a code on a suspicious listing, you trace it back instantly. Features: Log distributor shipments with one or more lot/batch codes each Instant reverse-lookup: paste a code, see which distributor it traces to Flexible matching for embedded sub-codes, or strict exact matching Flags when a code matches multiple distributors — a signal worth investigating Pro: export your full shipment log to CSV Nothing connects to Amazon — this only correlates your own shipment records against codes you observe elsewhere.
