“Woolworths, which owns Dan Murphy’s and BWS, and Coles, which owns Liquorland, First Choice and Vintage Cellars, leverage their duopoly regularly to undercut competitors, using heavily discounted alcohol as a loss leader. In March 2011, Foster’s was forced to withdraw the supply of key brands, including VB and Carlton Draught, when it learned that the supermarket giants were planning to sell them for $28 a slab, well below cost. The brewer said the discounting undermined their brands.”
