On Thursday 26 March 2026, Luxembourg’s Consumer Protection Directorate (DPC) announced that it had participated in an EU-wide coordinated check targeting misleading online promotions during Black Friday and Cyber Monday.
In total, 23 European Union (EU) Member States and two countries of the European Economic Area took part in the sweep, coordinated by the European Commission.
The DPC, under Luxembourg’s Ministry of Agriculture, Food and Viticulture, took this opportunity to more broadly verify the compliance of e-commerce professionals targeting consumers in Luxembourg, noted the ministry.
During the sweep, which took place from 3 November to 5 December 2025, the DPC monitored the price evolution of certain products across 34 online shops during the month preceding the promotions. This monitoring revealed that, among the 34 websites checked, twelve displayed promotions that did not comply with the provisions of the Consumer Code, in particular the obligation to display the lowest price applied during the 30 days preceding the promotion. According to the ministry, this information must be shown near the promotional price in order to allow consumers to assess the accuracy of the advertised reduction.
Following this, the DPC is contacting the Luxembourg-based professionals concerned to ensure they adjust their commercial practices. It added that it will inform the authorities of other countries if issues are identified with foreign traders selling to or delivering in Luxembourg.
A webinar for interested professionals will take place on Wednesday 29 April 2026 to present the findings and to outline best practices for price and promotion displays. To register, visit https://arcg.is/1i1Gvj2.
The DPC recalled that all professionals dealing with consumers, whether in physical retail or online, must comply with the Consumer Code. It added that free information material is available to support them, including the “Guide for professionals”, which contains four sheets dedicated to e-commerce and is accessible on the website pro-pc.public.lu.
On this matter, Martine Hansen, Luxembourg’s Minister for Consumer Protection, stated: “In a digital environment where online commerce does not stop at borders, coordinated action between Member States is essential to ensure effective consumer protection. I therefore welcome this cooperation at European Union level and my services will continue monitoring websites and online sales platforms using the tools provided by the European Commission.”
