How does international domain targeting work in eCommerce?

[TwitterpatedAU]

Hi

(1) I have setup multiple 3rd party domains so that I can geo-target different countries and regions. However I am not able to target an entire region, and I can only target individual countries. For example, I have setup the eu.example.com sub-domain to target Europe, but in the Shopify domain setup I am only allowed to target a single country.

(2) Furthermore, I have also setup an example.com domain with USD$ as the store currency (my main domain is example.com.au, with AUD$ as the store currency) and I have also set different pricing to sell on the example.com site (via payments -> manage -> countries/regions) however it seems the example.com store will just reference my AUD$ pricing and convert this to USD$ without applying the markup that I have set.

Can someone please help clarify how the international domains feature actually works? am I doing something wrong?

thanks

anyone from Shopify shed any light on these questions?
