Automatic price records that back the "regular price" in your Japanese dual-price sale displays.
In Japan, a struck-through regular price next to a sale price should be backed by recent selling records under the Consumer Affairs Agency guideline (the 8-week rule). The app records your catalog's offered prices from the day you install, checks each dual-price display against the guideline, flags displays your history does not support, and drafts the joint-disclosure stating when and how long the price was offered. Products scope only: no orders, no customer data. Not legal advice.
