Food For Less was an Australian discount supermarket chain owned by Woolworths Limited.
 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 later expanded into New South Wales and became the low-cost supermarket chain for Woolworths, competing with Franklins No Frills and Coles' Bi-Lo.
 The chain expanded on the purchase of 67 of the Franklins supermarket chain stores in New South Wales and Queensland by Woolworths.
 The "No Frills" stores then became Food For Less stores with a more upmarket appearance (edging closer to that of Woolworths) and also launched a new logo at the same time.
 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.
 The store in Maryborough QLD closed its doors in November 2016.
 However, due to competition from Aldi, Woolworths have considered reviving the budget brand.

A warehouse store or warehouse supermarket is a food and grocery retailer that operates stores geared toward offering deeper discounted prices than a traditional supermarket.
 These stores offer a no-frills experience and warehouse shelving stocked well with merchandise intended to move at higher volumes.
 Unlike warehouse clubs, warehouse stores do not require a membership or membership fees. Warehouse stores also offer a selection of merchandise sold in bulk, Typically warehouse stores are laid out in a logical format which leads people a certain way around the store to the checkout.
 As one enters the store they are directed down an aisle of discounted special buys when entering the store.
 From there the layout typically then leads to the fresh Produce followed by the Deli at the back of the store.
 Also included bakery and other departments similar to other supermarkets.
 Another typical feature of these stores is that the customer bags their own groceries which also helps to reduce the overall cost.
 Many warehouse stores are operated by traditional grocery chains both as a way to attract lower income, value conscious consumers and to maximize their buying power in order to lower costs at their mainstream stores.
 Notable examples of corporations who operate warehouse stores include United States chains Kroger and Albertsons LLC and the smaller Sacramento-based Nugget Market.
 However, WinCo Foods is an exception as it is a warehouse chain of its own and not part of a larger chain of traditional supermarkets like A&P, Safeway, Kroger, or Supervalu.
