Camera less 7% plus 19% German VAT: 1,567 EUR when it arrives. This doesn't include potential fees of your Bitcoin payment provider applied to the BTC rate.
Amazon: 1,564 EUR, delivered, all taxes included, will arrive on Monday morning when ordered today.
Sold and shipped from a EU dealer I enjoy all regulatory provisions regarding warranties and customer protection following EU law.
This is why it's not really worth buying expensive items from outside the EU. The only thing that makes the prices attractive is that they don't include extortionate taxes, but you'll almost certainly get hit with them in customs so it defeats the purpose. Then of course if there's any problems it's not worth shipping it back to wherever it came from. Far easier just to bite the bullet and pay the extra to get it from your own country or inside the EU. At least you have the warranties and guarantees then as well.
