Last time I used them, there was a surcharge to Europe added at checkout when using the English language printerstudio.com site, but no surcharge with the German language printerstudio.de site. Both ship from China via Germany, but there you go...
This was a few months back, mind, so they might have changed again, but it's worth bearing in mind. Both sites are identical bar language, so it's not too difficult to navigate the German version.
Edit: but then again, I don't know if printerstudio.de are doing the discount so that might negate the surcharge anyway.
