I'm using Shopify's new 'Local Domains' feature to expand my Australian store to NZ. However I'm surprised to see that although I've set up multiple currencies you can't base shipping tiers on the user's currency. So for example I can't say to a NZ user spend $150 NZD for free shipping, it has to be in the store's base currency (Australian) so they have to spend an amount in a currency they can't even see. Aside from the fact that I can't believe this got through testing, and that this feature is nothing more than some hreflang tags made to look fancy, does anyone know of an app or other workaround for this? Thanks!
