Just posted this in this weeks script produced Coles deal but thought it was worth a post in the forum.
This site provides historical prices on individual items in supermarkets.
For example, Mccain Lasagne

or Bananas (apparently they are the cheapest now)

Seems to only compare Coles & Woolworths.
