Hi Oana. The producer/seller determines and sets delivery options and you agree directly with the seller on terms of delivery. There are sellers who are delivering the products in Nis via courier service. If they are located in Nis, they might offer an option to pick up the products at their farm. When you search the market by location (enter the name of the city, in this case, Nis) you will see the list of sellers who both offer and deliver their products in that location.
