Is there any similar market wehere i can find single minis in Eu?
Are you looking for rares? What season? For just a mini or two you could go to ebay (i use ebay.com but also search for the krosmasters name in different languages, krosfinder.com will help you with this).
I bought some from:
som from the Ankama shop (french but google translate helps you all the way). Also here att bgg you can find some minis for sale. Good luck!
