Groupement Mousquetaires

View

Groupement Les Mousquetaires coordinates a network of independent retailers across Europe under banners such as Intermarché, Netto, and Bricomarché. Member-store owners use the group’s buying power, supplier relationships, and brand support to stock and run their shops, offering groceries, DIY goods, and automotive services. Unlike single-owned chains, it is a federation of privately owned stores that operate under multiple brands while sharing purchasing and services. Its goal is to help independent shop owners compete, grow their networks, and provide accessible, value-focused retail across Europe.
