Returned to playing with my sons and ran into the unavailability of the Monster Codex Box soon after.
Poked around and started seeing it pop up at under $40US on Amazon.fr (France's Amazon) as "New" and "shipped and sold by Amazon" with an expected pre-order release date (Thank you Google Translate!).
This would pass, go out of stock, and then it would post a new release date to pre-order. With Amazon's guarantee the next time it came up I jumped. Ordered on May 24th, it arrived today.
It came in its original cellophane as-is and the box was a bit beat up and smells a bit musty (sitting on a warehouse shelf somewhere I figure)so I figured at best it was used. Popped it open and it is indeed NEW, unpunched with unopened stands and all. Amazing. :)
Thought I would post here for those looking, you might want to keep and eye on Amazon.fr!
Hope this helps, they are definitely out there!
