CBA is a Hungarian-born grocery retailer that operates as an association of independent merchants trading under a shared national banner. It is not a single top-down corporate chain but a pooling of the buying power of many independently owned food stores, letting a local shopkeeper compete with multinational supermarkets while keeping ownership of their own business. It is distinctive for spanning a full ladder of formats — from a compact neighborhood convenience store, through a mid-sized full-range supermarket, up to a premium-positioned supermarket concept — so an operator can join at a scale that fits their location. Most stores combine a standard grocery offer with in-store fresh counters such as bakery, butcher and grill.
