That is a far better detailed explanation than my own STL and I thank you for sharing it with us as it reflects, albeit in better/greater detail, my own feelings that it is indeed the business model that needs to change in Big Australian Retail.
As you've said, they've shot themselves in the foot by sticking to a clearly outdated model for so long and are now feeling the pinch, which will turn into a vice-grip in very little time by the looks of things.
I think if small and medium business are able to take notice and mold their models around such emerged trends, then they'll be far better positioned to become the big businesses of tomorrow - Which would be a very welcomed change from the Duopoly of Retail, present in so many sectors of this country.

So do you think that this recent 'spot-sale' price drop is purely to compete with Target or to just clear stock?
