You're lucky - Amazon actually give a shit about the US.
They launched in Australia (the newspapers were predicting the end of retail). They have what, 30% of products available here? Then they launched Prime - except they obviously haven't hired anyone who has used Australia Post before. You can't expect a Prime 2 day delivery if you use standard Post.
All this, and they thought restricting access to the US version was a good idea.
Amazon Australia: death by 1000 paper cuts.
When eBay looks like a better option, you've really screwed up.
