Selection of supermarkets

Two conveniently located, large exemplar supermarkets from the major supermarkets present in Perth, Western Australia (Coles and Woolworths) were selected for this study. An Independent Grocers of Australia store was audited, but no SOBCCF were present. Discount retailer Aldi was not included in this study due to the limited range of foods sold⁽³⁷⁾ and because it had only just entered the Western Australia market at the time of the study⁽³⁸⁾. The specific stores were selected because they were identified as ‘optimised’ or examples of best practice for the chains, that is, they were large supermarkets with the most up-to-date layouts and displays and an increased likelihood of stocking a large range of SOB foods. A detailed description of the supermarket audit protocol is available elsewhere⁽³⁹⁾.
