D-Mart is an Indian supermarket chain started in 2002 with a philosophy of providing customers what they want at low prices. It focuses on serving the middle class with daily necessities at prices below MRP through strategies like low overhead costs, direct supplier relationships, and efficient warehouse-like stores. D-Mart has seen success operating this low-cost model in Western and Southern India and plans to primarily expand within existing regions to maintain tight control over real estate and distribution costs as it faces growing competition from other retailers and online players.
