I think my situation is pretty standard but I seem unable to find straightforward and exhaustive answers online, so here it goes:
Can anyone advice whether some or all of these options are possible, how to set this up and which Shopify plan can I use - I am willing to use Shopify or Advanced.
Hello vela idk what the reason you re talking about open so many stores if you can do just with 1 shopify store and operate all over europe. Shopify gives you a good option like for currency you can use BEST Currency Converter app. you can pick shipping location according to your needs. in case you re still confusing how to do this let me know i will help you out. you can all these by using a simple shopify plan.
