Show HN: A website that enables to search at every Amazon website (.it, .de,...) (yasse.eu)

I made this website because I found that it's possible to save money buying a product, for example, on amazon.de instead of amazon.it. The bad thing was that Amazon does not enable to search at every retail website at the same time. This website (yasse) does.<p>I hope you'll find it usefoul :)
