In addition, BİM launched an online shopping service for non-food products via the BİM MARKET mobile application in late 2021.

BİM continued its steady growth in 2024, opening 886 new domestic stores throughout the year to reach a total of 12,089 stores in Turkey by year-end. The company continues to develop while maintaining its commitment to quality and customer satisfaction alongside an effective cost management policy.
