You have a reference price but it needs to be adjusted to fit the countries where it is delivered and it cant be the same just by applying a simple exchange rate. Why you think I cant pay in GB? No matter what I do I CANNOT buy the product you are speaking of in GBP, I had to pay it in EUR....not even in USD..not allowed. why is that ? tell me ?

Besides that I agree, 400 % seems a bit much.
