Massimo,
I just bought a 85mm f1.8 and before that, compared the price of
different [mail order] shops.
Here it is (prices for the 85mm f/1.8, in BEF, divide by 40.34 to get it
in EURO).
Typical French high street price: ~23000
Typical Belgian high street price: ~21750
Typical UK high street price: ~17298

http://www.unbeatable.co.uk: 14415
http://www.ny-camera.com (german): 14008
B&H Nikon US: 12420
B&H Grey: 10350
You can notice the wild variation, even within Europe... I personally
bought from Unbeatable. They have shops in West Sussex (shops are called
Capital Sound & Vision) where you can buy at the same prices.. and save
the shipping costs. Items are grey import but I don't really care,
especially for a lens.
If you add shipping and custom fees to B&H, it comes really close to
European prices. I wish I lived in the US... (well, for this, at least).
Hope this helps,
Nicolas.
