I really want to help, but I got my set via some strange ways
A friend of mine (working for a big german "component supplier of the automobile industry" with good connections) ordered it directly from Eibach Germany. First they said they will not import just one set, but after 3 month they suddenly sent it to me. Wow.
With tax, customs & shipping I paid 300EUR, so you can see how much profit they make under normal circumstances...
I also got my Bilstein shocks directly from Bilstein Germany
