Price Radar Online for France

Price Radar France: who is really the cheapest online retailer?

Shoppers assume one store is reliably the cheapest. The prices say otherwise. This Lengow study, powered by NetRivals, is the first edition of Price Radar: it compares 328,840 identical products (matched by barcode, EAN) across 375 online retailers active in France between January and May 2026, and names the retailers that come out cheapest in each category. Amazon is the single cheapest retailer more often than anyone else, on 18.8% of products. It still loses two categories out of four, and the price of the same product runs as much as 95% higher from one seller to the next.

What you’ll discover in this study:

  • The cheapest retailer in every category: the Top 8 cheapest retailers in each of Beauty & Health; Sport, Outdoor & Cycling; DIY, Home & Garden; and High-Tech, with the share of products where each comes out cheapest and a net score for every entry.

  • Why Amazon’s 18.8% doesn’t make it cheapest everywhere: Amazon is the single cheapest retailer on 18.8% of all products, more than any rival, yet it tops only High-Tech (30.3%) and DIY (22.6%), sits third in Sport behind Bike24 and Deporvillage, and falls to eighth in Beauty behind Perfumesclub.

  • The net cheap score, who’s really cheapest versus who just looks it: a metric that separates retailers that are systematically the value option from marketplaces that look cheap on a handful of products but rank most expensive far more often, Rueducommerce (−19) and Auchan (−11) among them.


In this study we explain:

  • What we measured and why: displayed prices for identical products matched by EAN across at least three retailers, averaged over January to May 2026, and why this reads price competitiveness rather than sales.
  • How four categories price differently: where Amazon wins on price, where specialists like Bike24 and Perfumesclub own their aisle, and which categories show the widest spread between cheapest and dearest.
  • How to read the net cheap score: why being cheapest most often is not the same as being the best value, and how the score exposes retailers that are the dearest more often than they are the cheapest.

This study is for:

  • Brands and retailers benchmarking their price position in France against Amazon, marketplaces and category specialists, aisle by aisle.
  • Pricing and marketplace managers deciding where repricing and dynamic pricing earn the most, category by category.
  • Category and merchandising teams who need a clear read on where price competition is fiercest before a launch or a category expansion.
  • Pricing and e-commerce analysts who want benchmark figures (price dispersion, cheapest-share, net score) grounded in real January to May 2026 e-commerce data.
