Browsing the Officeworks website, I found this item in clearance. Quite a good price considering the non leather ones are virtually the same price also in clearance. This price is pick up only so call around to see if your local Officeworks has stock. Alternatively try the ordering trick mentioned in other posted Officeworks items to see if it is available near you.
Go to the officeworks website and search "clearance" and there is a load of other ridiculously cheap stationery and other things that might interest you.
… and 99% of the 'clearance' items aren't in stock / available to order, because their system shows things that might only be available at one or two stores at that price (even if their distribution warehouses that serve their online website don't have any).
