Lowest price should be shown for the last 30 days before the announcement of the price reduction

Problem/Motivation

Price reduction claims such as “was € 50, now € 25” can be misleading if the initial selling price (known as “anchor price”) has been inflated. In all EU countries traders are obliged, when offering a discount, to indicate the lowest price applied to the item at least 30 days before the announcement of the price reduction.
This information allows you as a consumer to assess whether the discount is genuine or not.
