Why don’t Bulevip and PromoFarma cost the same?

PromoFarma costs 3 % more per capsule than Bulevip (€0.263/capsule against €0.256/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: different brands in the catalogue, products with declared additives. Bulevip mostly sells one brand, Mega: 33 % of its catalogue in this category. PromoFarma spreads its own across 14 brands. A store selling its own brand skips the manufacturer’s margin and can cut the price without touching the formula; a reseller pays that margin and passes it on, and in exchange carries brands the other does not sell. What the pages of both declare: anti-caking agents, colourings. 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.
