If a customer enters their address into the shipping calculator, then the following will happen:
If your store has shipping methods set up for their location, then the shipping cost will be displayed on the WooCommerce product page.
Alternatively, if there are no shipping methods for their location then a message will appear explaining that no delivery methods are available.
If you allow customers to collect orders from your location then we recommend adding a 'Local pickup' shipping method. This is independent from the customer's location, so it will always appear - even for customers who you will not ship to.
