The webshop is a scam, as they never have stock.
I preordered a box set on the 6th of January. Paid the price in full. Product was supposed to be shipped on the 20th of January. My order was confirmed as being available and scheduled to be shipped on time. I cancelled my preorder at the end of May, as I still did not get my product. From January to July the box set I wanted to buy was never available on their direct webstore. Ordered from a different retailer that told me they can get it, as it is available in the EU warehouse. It is now July, and the box I want to buy is still "Temporarily unavailable" or "Out of stock".
