原文外掛簡介
Every discount in an EU shop must show the lowest price of the previous 30 days. WooCommerce does not do this by itself.
Since 28 May 2022 the EU Omnibus directive (Directive 2019/2161, article 6a of Directive 98/6/EC) requires every price reduction announcement to state the lowest price the product had in the 30 days before the reduction. Consumer authorities in Germany, Poland, France, the Netherlands and other member states enforce it. A “was €100, now €80” without that line is a violation.
Nadirmark records every price change of every product and variation, calculates the correct reference price for each sale and shows it under the price, on product pages, in shop lists and for the selected variation. When the history cannot back a figure up, Nadirmark shows nothing instead of a wrong number.
See it in two minutes:
How it works
Activate the plugin. From that moment every price change is recorded, whichever route it takes: the product editor, quick and bulk edit, the REST API, CSV imports, scheduled sales or plugins that write prices directly.
Import prices from your past orders under WooCommerce → Nadirmark → Tools. Every paid order proves what a customer paid on that day, so the 30-day window is covered right away for products you have sold.
Put a product on sale as usual. Nadirmark adds “Lowest price in the last 30 days: €…” in the language of your site (built-in wording for 15 languages, or your own text).
What makes Nadirmark different
Never a figure you cannot prove. Nadirmark knows exactly which period its own records cover. When the 30-day window is not fully covered it hides the line instead of showing a reference price it cannot back up.
Correct rule, not just a minimum. The reference is the lowest price in the 30 days before the reduction started. When you lower a running sale further, the reference from before the first reduction is kept, as the directive allows. A rolling “last 30 days” mode is available for shops that prefer it.
Tamper-evident history. Every record is chained to the previous one with a SHA-256 hash and stores who changed the price and through which route. Retention is configurable (24 months by default); the latest price of every product is always kept.
One record per change, not per page view. Small table, fast pages, even with thousands of products.
Variations done right. Each variation is tracked separately and the line follows the variation the customer selects.
Block themes and classic themes. Works with the Product Price block, classic templates, shop loops, related products, a shortcode and a template function.
Switch without losing history. Imports the data left behind by Omnibus (iworks) and WC Price History.

Nadirmark Pro adds a campaign planner (which reference price may you show on the start date, is the planned price a real reduction, and will Google Shopping display the sale label), a fake-discount guard that shows non-reductions as plain prices, a verified audit export and printable report, and a daily alert e-mail. Pro is sold separately by the plugin author; the free plugin is complete on its own.
Good to know
Nadirmark is a tool that helps you apply the price-reduction rules; it is not legal advice. Rules on progressive discounts, perishable goods and products newer than 30 days differ per member state. Check the guidance of your national consumer authority.
