I know the UK have their own site and I'm guessing some other European countries too but which other countries are able to purchase almost anything from Amazon.com and does what they are able to purchase depend on the nature of the goods being sold?
It depends on what items are being sold or by who... but theoretically most of the world can buy from Amazon. Many Australians buy from Amazon.com. I have also purchased from Amazon.com (I am in the UK). There are also a number of european sites, japan, china and canada.
