Fishpond, a book, toy and game online store in Australia, is selling Song of Scarabaeus for only $7.95. That's 4 cents cheaper than Amazon (well, it's actually only 1.3 cents cheaper, taking into account today's exchange rate). And Fishpond has free shipping with no minimum purchase. They say free shipping is for a limited time, but it's been free since before Christmas.
They have to order the book from America so shipping time is 2 weeks, but as you can't even buy the book in Australian stores (other than, allegedly, a couple of city stores), it's a good trade-off.
No idea how long this will last, but their list price is $22.99. Yes, that's outrageous, but we Aussies are used to paying ridiculous prices for our books and CDs. (My sister used to order text books from the UK because it was cheaper than buying them here, even after paying shipping.) Actually, you can get it cheaper from some of the other online stores listed in my blog post here, anywhere from $10-$16, but you may have to pay extra for shipping.
Also, if you're the first person to review the book on Fishpond and write 50+ words, you get 20 cents store credit.
