Just down at OW in Chadstone and saw they're flogging off a bunch of expired canon cartridges for 10c each. Not sure if there's anyone out there who wants expired canon 3e cartridges, but if there IS someone who wants these I can't imagine anywhere selling them any cheaper than this.
Not sure if they're available at any other OW either, just saw them at Chaddy. Also, there was a box full of packs of clear plastic exercise book covers for 10c a pack each, but honestly they looked like they were worth about that much so I didn't bother taking a photo.
These are right near the front door next to the checkout for anyone interested.
Hope someone finds this useful!
