That is no problem; our website works globally and has smart links that will refer people to the correct bookstore location. So, if a visitor is in the UK, it will take them to the UK version of Amazon and Bookshop.org. If a visitor is in the USA, it will take them to Amazon USA and Bookshop USA. If a visitor is in India, it will take them to Amazon India. And so on.
Here is more info on our smart linking and how it works regionally: https://support.shepherd.com/hc/en-us/articles/4406611812369-How-does-Shepherd-work-with-global-audiences-
[We do have a small bug we are working on now to fix with Canada-only links, but that should be resolved soon. ]
