Clearance item at all Aus Post stores. Check the clearance bin or ask the staff if they aren't on the shelves. Might scan at $6.99, but just let them know it's a $0.99 clearance item and show them the receipt below:

EDIT: Just spoke with my manager and he claims it is on the system. Every Monday stores check their system for updated prices/clearance item. This popped up and he claims all retail stores should get it. Item in question is low in global stock and they want to get rid of it. Either the stores haven't bothered checking the system, assume it's a pricing error, don't want to bother printing it and displaying it, or are keeping it for themselves. Debate the issue with this statement if you please, but don't push it if they keep denying. Sorry for any inconvenience caused.
How much for shipping? Or is it too presumptuous to assume they would post it?
