Some places to buy my book in Australia (sadly, all on-line):
$20? Not bad for Australia.
Look at that RRP: $34.99. And that's in Aussie dollars, not that worthless green paper. But it's discounted to $22, which is reasonable.
Ebook only, but hey - free delivery!.
OK, even I wouldn't pay $35 for this book, and I think it's the best book of the year. I can say that because GRRM hasn't released a GoT book this year. But then, I guess you can say that about almost any year.
This is the best price, only $17.69, but they order it from America, so it takes a couple of weeks. So better order two, for when your partner swipes your copy!
