Seoul's Geumcheon-gu district is launching an online marketplace from September 8 to 18 to sell products from farms in their sister cities at a discount due to COVID-19 and flood damage. The products, including black garlic extract and anchovy sauce, will be sold at 10-20% below market price. Customers can find product information and place orders on the district's website or through promotional materials at community centers. Orders can be paid for and delivered via courier starting from September 21.
