This is not a question per se, more like sharing a solution I found.
I needed to make my website multilingual and multi-currency a while back. I really struggled to find solutions meeting my requirements, so I came up with a solution:
Use Weglot for the translation (no page duplicate, can translate the checkout)
Duplicate the shop section of my Squarespace site for the 2nd currency (and pay Commerce again)
Set up Geotargetly to redirect people according to their location
Use Datafeedwatch to list our products on Google Shopping and Facebook Catalog
I wrote a detailed guide on how I've done it. Hopefully, it helps someone.
