I don't think you need to import or pick up anything at all. I would mail with the regular mail directly to your house. It's all on one CD that fits to your mailslot. Since you guys are part of the EEA Agreement you shouldn't need to pay any importing fees at all. Or do you even pick up all of your personal mail from outside of the country at the airport?
I've mailed applications, music & games I've created in the past to many countries in the world, always through the regular mail and never heard of this before.
Also I always sent it as a gift, if I'm asked to specify what's in the enveloppe. It will be regarded as personal mail from me you.
I do see all of the possibilities of a website for sure and at my current webspace provider I can easily expand, but before doing so I need to make some good revenue to cover the expenses.
So for now it will be mail only, sorry. IF the business grows, I'll do downloads for sure, but for now that's not the case.
