This was something, I didn't know about Grace Bros until I saw this. Once upon a time, it was possible to do all your shopping in one store, even your grocery shopping. In fact, they were happy to brag about the future of supermarket shopping.
I am not a fan of the duopoly between Coles and Woolworths and if the Department Stores want to stay in the game, it might mean going back to some of the ideas of the past. One of them is supermarkets. Billions are made by Coles and Woolworths each year and that says something. Spending on food is going up. Helped by cooking shows such as Masterchef or My Kitchen Rules, people's interest in cooking is on the up. Why cannot the department stores join the party? David Jones fortunately still have their Food Hall in their Market Street store, why not build on that? Even creating their own chain might be a start?
