Do you have products in your WooCommerce shop that you for some reason can’t sell to customers in certain countries?
If you do, this is the plugin for you!
For each product in your shop, you will be able to specify a list of countries that you may sell that particular 
product to. Or, you can specify a list of countries that you don’t want to sell to.
Geolocation is used to determine what country the visitor is in, if their country is not in the approved list of countries 
for the product, the add-to-cart button will be disabled.
You will need WooCommerce 3.0 or newer.
Does support translation.
