In most markets the cheapest store changes from one category to the next. Spain barely plays by that rule. This Lengow study, powered by NetRivals, compares 230,535 identical products (matched by barcode, EAN) across 404 Spanish online retailers between January and May 2026, and names the cheapest retailer in each category. Amazon is the single cheapest retailer on 18.7% of all products
and fights for the lead in three categories out of four. The one aisle it can't take is Sport, where cycling specialist Bike24 comes out cheapest more than twice as often.
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 Electronics, each with the share of products where the retailer is cheapest and a net score.
How far Amazon's reach stretches in Spain: cheapest in Electronics (30.7% of products) and DIY (20.4%), a narrow second in Beauty behind Perfumesclub (24.6% against 27.1%), and beaten outright only in Sport, where it sits third.
The net cheap score, real value against the look of it: a measure that tells retailers offering steady value apart from those that flash a low price now and then while ranking dearest far more often, ManoMano (−18), PhoneHouse (−15) and Bergfreunde (−16) among them.
How wide the price gap runs on the same item: a median spread of 46% in Beauty and 39% in Electronics, and identical products selling for as much as 95% more depending on which retailer you open.
