Food For Less: 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.

Super Epsa: Super Epsa is the former name of a supermarket chain in Lima, Peru, which was founded in 1953 by ALDO E OLCESE as Super Market S.A.  The importance of this Supermarket chain lies in that it was the first occurrence of an American-style supermarket in Perú.  Aldo Olcese was born in Lima on December 29, 1922.  His father was a hard working Italian-Genoese immigrant.  Aldo went to the United States in 1946 to study Business Administration at the University of Texas at Austin and he graduated in 1950.  During his lifetime, as a student in the United States, he was impressed with one Super Market close to his residence where he frequently shopped together with his wife, and since then he thought it would be a great idea to carry out the same kind of self-service Super Market in Perú.  In 1953, and for the first time in the Peruvian History, the first supermarket was officially opened in Av Larco 670, Miraflores, with great success.  After 20 years in the Super Market business, the company opened a total of 14 supermarkets scattered throughout the Peruvian capital.  Therefore, we can consider without any doubt, that Aldo E Olcese, was the pioneer or first person that brought the first self-service Super Market to Perú in 1953.  His great-grandson, Carlo Olcese, is former Eminent Archon
