The price of K-1 at the factory door, paid by the Distributor (in Yen), has not changed.
The cost of Yen to the Distributor (Pentax Europe) in Euro has changed dramatically in recent months as the price of Yen has risen.
The retail store price by country is a function of the Distributor price (in Euro) + EU VAT rate + individual country and local (if any) VAT rate plus greed where applicable.
I paid almost $2,000 for my K-1 in a B&M store including 9.37875% Sales Tax. But they put a 64GB Lexar card, small Kenko flash, travel tripod and a Rocket Blower 'In the Bag'.
