Ixsoft has Dominions listed for 50€ no shipping costs. It's the cheapest offer i found for germany. You still have to be 18 of course (since it's an import game) though i guess that's not a problem for the majority of Dom players. (call me age biased if you wish )
They list it as coming "start of october" and i did not yet recieve an email that my copy is on its way, but i hop they'll be able to start delivery next week or so.

edit:Maybe someone from Shrapnel will be able to enlighten me about when the deliveries for european distributors will arrive?
