@paul2009, thanks for your posts on this topic. It's good to hear that you have been campaigning for Squarespace to address this natively, and really sad that after 11+ years of Squarespace Commerce they still haven't addressed it. If a platform like Shopify can display local currencies all the way through checkout, it seems insane to me that Squarespace would not offer/address this.
I've sent an inquiry about Currencies pricing/timeline via the sf.digital site. Hoping to implement it on a site I'm building right now.
