Product can ship to your location
Connect GeoIP with Countries available for shipping.
So customer A lands from Germany, they will see shipping is available to Germany in the product page or other area. Because GeoIP detected they are from Germany and Germany was available and had shipping rates defined.
Customer B from Canada is informed This item does not ship to Canada, because GeoIP has determined they were from Canada, but no country for Canada was active or shipping rates were not defined.
This saves many emails and customer service, do you ship to my location. Plus it increases sales that the customer is presented with a greeting that the item can be shipped to their location before they add-to-cart.
