Ask HN: How did you ship your Kickstarter

I'm getting ready to launch a notebook on Kickstarter (https://www.kickstarter.com/projects/1498851720/206468379?token=2c4545f2). My issue is that I want to be able to ship books internationally, but it's damn expensive. I went to the post office today (I'm in the US) and it's like $25 to ship one book to Europe or Australia. Is there any kind of a service where I can bundle all my books together and ship them to one location, somewhere in the UK for example, and then have them each shipped domestically throughout the EU? I'm assuming that would be cheaper than sending each one individually from the US. If this isn't already a service, then why not? I refuse to believe I am the first one to have this idea.
