PS one more info: The creator of Relicblade has answered shipping related questions on the Relicblade Facebook page
Shipping still costs a bit (but not extremely so) if one just orders the book since everything comes from the US and is then being shipped from the EU but the idea seems to be that people can order other stuff like miniatures in the same order as well if they like.There also seems to be free shipping for orders over 100 $.
I think that is a fair offer, especially for a one man-company (looking at how he talks in his videos about his game really is a joy. He seems very passionate about it!). I will probably add a few Relicblade models to the adventures in my Felstad-inspired city
