spielelite.de has a .de ending but does ship from outside the EU, as much as i know. So, yes... a Sky3DS costs more than 20 Euros, so you have to pay customs (english for "zoll").
Spielelite will sure mark the sending as a gift, but the guys at the customs often don't belive it. If you have to pay, chance is about 70%, you'll have to pay 20% of the product price AND the shipping costs. The card costs 78 Euros on spielelite, 20% of 78 Euros are about 16 Euros. Sad, but Germany is bare ass and taxes it citizens hard.
