Why don’t Amazon and HSN cost the same?

Amazon costs 135 % more per kg than HSN (€58.17/kg against €24.73/kg, 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. Price per kg and price per dose point to the same store, so the dose does not erase the label difference: HSN is cheaper both ways. HSN mostly sells one brand, HSN Raw Series: 86 % of its catalogue in this category. Amazon spreads its own across 29 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.
