Once every 3 hours you can request a product type you want to from your neighbors. You can only request products that are available at your level. Exceptions are construction materials, keys and seashells. You have to get these yourself and cannot request them in the Neighborhood chat. Requests are made through the chat window. The amount requested is set automatically. Once the request is completed, you can collect the requested items from the chat window. If you don’t take the items from the completed request, you cannot make a new request.
