This is all very simple ...
Norway is outside the EU and it is quite expencive to have marginal products like amiga-stuff sent here. Only way to cut the cost is to make sure the number of items in a shipment is big, only way to get it big is to await for enough customers to order, and again this is amiga, so it doesnt happen quickly.
So, please, if you want stuff ASAP, order it from Germany, UK or Poland or where-ever yourself, but dont be shocked by the price you have to pay in terms of package, transport and customs. ;-)
