Hmm, I am from Germany, too. I don't have a Kindle, but I use the Android and other Kindle Apps and I have purchased several books and even a magazine subscription using my german credit card (and never gave them an additional address in the states). Also, I can sign into Amazon.com using my german Amazon account, I don't remember when they changed this, but at some point it just worked. I am not going to move to the German Amazon Kindle Store, as for example that magazine subscription is not available in the German Kindle store. To me, that is the real problem at hand (besides the fact that they shouldn't expect you to pay the same amount of money for a digitally distributed version as you would have to pay for the dead tree version, but that's a totally different issue, which has already been discussed a lot).
There's no problem in using the Kindle store from other countries -- you're just paying $3-$5 dollars more for exactly the same thing as you'd get if you are registered in the US.
You can check this by going to the same kindle page with an account with a US-based address, or a proxy in the US. For example, here are the prices for two ebooks, one from .nl and one through an anonymous proxy:
I think sometimes it's not that people are cheap, it's just that the internet's been out for almost 20 years and these legal barriers that screw the customer don't need to exist.
Say what you like about bittorrent, at least it's egalitarian.
The surcharge has nothing to do with which country's store you use. Users in UK/Germany/Switzerland/Austria (and Lichtenstein?) do not have to pay the extra fee regardless of whether they use .com, .co.uk or .de. Users in other European countries pay it no matter what.
(E.g. your example book shows up as $4.03 from Switzerland).
