No store is cheap at everything. This page does not name a winner: it gives each one’s median in every category they share, so you can see where each wins and by how much. Prices are from the last collection and change; catalogue and certification change far less.
† Some links are affiliate links — they do not change the ranking
Some store links are affiliate links: if you buy through them, this site may earn a commission at no extra cost to you. It changes nothing in the ranking: the score is computed beforehand and without reading those links, and products with no affiliate programme appear exactly the same. How it is calculated.

The median is not the price you will pay. It is the midpoint of that store’s catalogue in that category: it tells you where to start looking, not what to buy. That is what each category table is for, where the specific row counts.
