Just as an update from my side: Thalia.de doesn't deliver the box anymore.
I am a bit sad though, this would have been my first box of at least a couple I would buy, but seeing as there is no real alternative to gathering a lot of the same I am probably going to explore different solutions than this. meh..
Although I understand it business wise and all that, I am personally a bit sad that I can no longer buy this. For me this would be the start of a fine collection as I really want more than a couple of the same monster which the other sets simply do not provide enough.
Thanks Feyliya for the pointer to Thalia.de though. I am trying to ship it to Netherlands but their website is the slowest thing ever.
