It was originally established in Queensland, where a discount 'food barn' chain operating as "Jack the Slasher" was acquired by Woolworths in the early 1980s.

It is positioned as a budget low-cost chain and while it mainly sells dry groceries and frozen perishables only, a small number of older stores also sell fruit and vegetables. Since 2010 most stores have closed or been refurbished and converted into Woolworths. As of April 2016 only 2 stores remain open, Roselands and Beresfield NSW.
