Due to limits and limitations on the size of Shopify shipping profiles, we're sadly not able to offer shipping profiles to every country. We've added 50+ of the most shipped to countries however, this will mean on some of the less shipped to countries, customers may receive a message that the product can not be shipped to their location.
If a country is missing which is a large market for your book, you can reach out to the support team to get it added onto your store.
Alternatively, if you wish to access all rates through Shopify, you'll need to reach the below criteria as specified by Shopify.
