For many years, Australia's supermarkets tacitly agreed that the cheapest loaf of bread for sale would be a 650 gram white loaf for $1. Now Woolworths and Coles have decided that's apparently too expensive, and are selling that same white loaf for 85 cents.

The Australian Competition and Consumer Commission (ACCC) is taking supermarket giant Coles to court, alleging that it has engaged in "unconscionable conduct" against suppliers. Why does that matter, and what difference might it make to your supermarket experience in the long run?
