Phantom Markdown shows the reference price the EU Omnibus Directive (Article 6a) requires the lowest price you offered over the last 30 days automatically. It records your prices every day, works out the 30-day low for each product, and shows it as the crossed-out compare-at "was" price, saves it to a metafield for your theme, or both. If a compare-at price is set too high, it lowers it to the correct amount.

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…
