Yes, you can get free shipping through booko.com.au but this way you can use the QANTAS online mall and still get free shipping.
Cut and paste from the email:
It's our 11th BIRTHDAY and to celebrate we have a Free Shipping offer for you and your family and friends, (you can forward this email to them if you want).
I started Booktopia on a $10 per day budget on the 4th February 2004. It took 3 days to sell the first book. Now we sell one book every 10 seconds. Thank you for being part of our journey.
Just place an order before midnight, Tuesday the 10th of February, using the code below and pay absolutely nothing for shipping!
