Shipping costs from the US are absurd in my experience, but shipping to the US is often not bad. I don't have much experience with shipping shaving gear, but I have a classic automobile (an Alfa Romeo) and I often get parts from England and The Netherlands for it. Shipping via Royal Mail from England is great - it's only a little more than getting parts shipped from the East coast (I'm in Colorado) and often faster. Like 3 days - it's amazing.
A few years ago I had a custom bicycle frame made in England. It cost I think $60 to ship it to me. The frame builder and I had a miscommunication and the first frame came to me wrong. It was definitely my fault at least as much as his but he agreed to build me a new frame but I had to send the first one back so he could sell it in his shop and recoup his costs. It was over $200 to ship it back to him! Ouch.
