Easy fix for price gouging

Transparency is the fix. All the govt. needs to do is make Woolies and Coles provide anyone who wants it with their price lists via a website. I can guarantee that within weeks if not days app developers will have created all sorts apps and websites that show specials, comparisons, shrinking products and God knows what else. Zero cost to the govt and trivial for the supermarkets to do. Only thing the govt needs to do is check the price lists are correct
