Phantom Markdown ‑ EU Omnibus

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. Your selling price is never changed. More regions coming soon.
