A Martin costs double the price in Europe ,is this normal?

Let's take for example the D-10E Retro Nat. On Martin's site its 999 Dollars or 850 Euros .  American retailers typically sell it for 899$ which is even lower. Ignore that . In Europe the same guitar costs 1385 euros that is 1624 $. So it is almost double the price . I understand the import fees etc. But in any case the price should not be that high... So who is to blame for that ? retailers?
