As I was leaving OW in Glen Waverley I noticed these under a temporary trestle table set up in the entrance.
Not the "bargain of the century-entury-entury" but I still picked up 3 or 4 because I'm thrifty like Macklemore.
Billed as a clearance item so may not be around for long.
Plan your year, scribble down mathematical theroms, or eat your ramen over them like a Boss.
Been like that for a few weeks now. I also bought a few.
If you wait a little longer, from memory, it becomes around 50c near the end of March (if last year was anything to go by).
