Amazon doesn't strike me as being the best of the bunch in terms of i18n, really. Here in Italy, their presence is kind of limited in terms of countries/languages where they are present: only Germany, France and UK. Granted, it's more difficult for a company trucking in physical products to move into new markets, but they seem to be taking their sweet time about it.

Google is a bit better, but still strikes me as very US-centric in some ways.
