If you are interested in a product from another user that is far from your location, you can use the Wallapop shipping service. In this case you will have to pay the shipping cost. To complete the shipment, you must submit an offer through the conversation. If the seller accepts it, a code will be created for them to ship. Shipments are handled through Correos (the Post Office). You can follow the shipment through the app or on the Correos website with the shipping code that they provide you.
Remember that purchases made with this service must have a minimum price of 1 euro and a maximum of 1000 euros.
