It stands by consumers who seek quality and affordability through a unique buying experience, with its 389 physical stores across mainland Greece and the islands. It also has a dark store to serve its e-shop in Attica, and a state-of-the-art Logistics Centre in Kavalari, Thessaloniki, which is the largest in the Balkans.
It invests in technology and infrastructure that fully cover retail and wholesale trade, while its easy-to-use e-shop is certified with the ISO 9001:2015 management system standard for the proper execution of orders, thus ensuring the quality of products and services; it has evolved into a contemporary market place, where customers have the opportunity to add more to their shopping basket than groceries, such as partner brand-name products coming within other categories (pharmacy, pet shop, technology, homeware products, etc.).
