Manual hunting

- Easy to end up with junk, accessories or damaged goods because sellers are hard to vet in time.
Automated with JapanScanner
- Scans 24/7 on your plan’s cycle and alerts you via Telegram/Email as soon as a listing matches.
- Filters junk, accessories and damaged goods, and shows seller reputation when data is available.
- Calculates how far below market price a listing is to spot good deals (paid plans).
