Bigsale Mart Jaesongjeom is a 24-hour supermarket near the Dongbu District Office in Jaesong-dong, Busan, selling fish, meat, vegetables, and fruit. Promotional items appear frequently, and the local store receives new vegetables every day. The store has a short layout that makes products easy to find, and long-serving staff recognise regular customers. There is no parking space, so it is inconvenient to reach by car.
