Woolies has knocked sweet corn down to $1.00 each this week, which is a $3.50 saving on its usual $4.50 shelf price, and cheaper than anywhere else right now. Coles is sitting at $1.70, Aldi at $3.99, and IGA at $4.10, so if you've got a Woolies nearby, it's the obvious pick. Chuck a few in the trolley for the weekend BBQ or slice them up for school lunchboxes, at a dollar each you can afford to stock up. These specials don't hang around, so grab them before they flip back.
