Are you from Italy?
I just received my Samyang 12mm from foto-klik.si for €299 (I'm from the Netherlands, and the price is including shipping)
It's a camera shop in Ljubljana - Slovenia. Orders can be payed by Paypal.
It's send by GLS with a great track & trace
I really recommend them considering this shipment
OH, and it comes with a free Samyang 67mm protection filter ! (not that I use one, but it's the thought .. )
