Totally agree, international shipping just came out at $80~ dollars for me. It certainly killed my excitement pretty quickly but still went ahead with the order considering it was still less than £120 which is pretty much what I decided was my max limit.

It's also two packages in one - the first one to get the set to you, and the package includes the shipping and package to ship the sample back to the US.
