Why don’t DosFarma and PromoFarma cost the same?

DosFarma costs 11 % more per capsule than PromoFarma (€0.600/capsule against €0.542/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), products with declared additives. DosFarma 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. What the pages of both declare: anti-caking agents. An additive is not fraud, but it takes up grams that are not active ingredient and is cheaper than the active ingredient: where more additive is declared, the price per capsule drops without the product being better.
