It is possible they all received the same amount, Nedgame isn't as well known as Bol.
The listing on Bol was weird, it didn't say SE and the language was German.
The SE on Bol was put on the website in the morning and Nedgame was on a midday.
There are 51 GM stores and they all have 6 copies available (3 for Conquest and 3 for Birthright) so let's say 300 or more copies available.
I have no idea what I wanted to type.. I am doing so much stuff at once :P
