Why don’t Amazon and DosFarma cost the same?

Amazon costs 38 % more per capsule than DosFarma (€0.183/capsule against €0.133/capsule, medians of both catalogues). That difference does not come out of nowhere. These are the data that explain it, with each store’s figure alongside: capsules per pack (median). Price per capsule and price per dose point to the same store, so the dose does not erase the label difference: DosFarma is cheaper both ways. Amazon sells bigger packs, and a big pack spreads the same tub, the same label and the same shipping over more capsules. Part of the price gap per capsule is this and not a discount: comparing one store’s small pack with the other’s large one inflates the gap.
