Looks like an opening special for this new IGA supermarket chain in Doonside. It's meant to be IGA's new national brand for supermarkets competing with Aldi, but with name brands (yeah let's see how that works out for them).
Normal price seems inflated but this is actually pretty decent. A few other cheapies in store.
Might give it a try for 1.99 was 3.50 when i was there last week
