Product language flags - PrestaShop

Since 2023, every discount must show the lowest price from the 30 days before the promo. Simple — until you count it by hand across hundreds of products. This module handles it: it records every price change and shows the required notice below the price whenever a discount is active.

It captures changes from any source: editing, specific prices, file import. It also adds the net price next to the gross. The history is not deleted on uninstall (the law requires keeping it) — unless you enable cleanup in the settings.

It is for anyone who runs promotions regularly and would rather not risk a fine (which can reach 10% of turnover). Once set up, it runs in the background for the whole catalog — you never have to remember it at each markdown. The clear notice under the price also builds customer trust by showing the deal is fair.
