Ah, yeah, physical copies on my website are only setup for shipping to the Americas. That said, shoot me an email at alex@newyearstudios.com and I can ship you your order from my stock in the UK. It's really just an issue with my site. Sorry for the confusion and or bad user experience there.
You can also order from Johan Nohr's site out of Sweden: https://pittrapshop.com/products/mork-borg-compatible-core-reference-cards
