I'm in New Zealand and I can see the Aura at the top of the
http://www.kobo.com/ereaders page. Clicking on it takes me to
http://www.kobo.com/koboaurahd. There's no "buy" button on that page, just a "Where to buy" link that goes to
http://www.kobo.com/koboaurahd/wheretobuy/ and that lists a bunch of websites.
