Yeah, I will cover EU.
The 25$ is the quote for shipping in a box, because people were concerned that the springs might get damaged in a padded envelope.
As I posted earlier this is not reasonable for a set of 11$ springs in my opinion, but that's for you to decide.
The prices for shipping the switches you were talking about are for shipping without tracking.
If you don't need tracking it would be cheaper, but I don't take responsibility for lost shipments.
