Well this is embarrassing. Two posts in a row from our old mate theearth. But they're just too good not to post on OzB. So all pride aside, and full credit to the great man. Sale starts Thursday. No idea if it's instore only, or available online in which case delivery should be free.
EDIT: Thanks to the link provided by Firey1989, seems this price is available now with free delivery. Store stock levels should increase Thursday when the catalogue sale officially starts.

Update:
There appears to be issues with their cashback form. They advise the following:
use Other, and the Other and then type in the full name of the store
Officeworks is listed as an authorized seller.
I had that exact reaction when i got the error! but yeah, noticed the number for customer services and the person i spoke to couldn't have been nicer. sounded like shes answered the same question a few times already :P. So as soon as you get passed the "location of purchase" section it leads straight to the personal details and also it requires a copy of the receipt so just get OW to email it to you when you purchase it.
