I want to set up local delivery only with no shipping to other parts of the world or areas? I am unsure how to do this. When i go on my site and place an order it allows people from other provinces to place and order. It does not by default say no shipping to this area.
I would like to set up so people can place orders choose pick up from store or delivery to local areas only with no shipping. How do I do that?
