FOSTER'S has taken its war with Coles over the price-cutting of beer and wine direct to bottleshop aisles, with employees of the brewing giant dispatched to buy up all bottles of Penfolds "Baby Grange" being sold at below cost. In guerrilla-style raids on Coles First Choice stores, staff from Foster's, which owns Penfolds, grabbed about 100 cases of the winemaker's celebrated Bin 389 being sold at the loss-leader price of $37 a bottle. The celebrated shiraz wholesales for $44 a bottle and usually costs drinkers $65 a pop.
