Five major non-food chains in Syracuse, New York were surveyed to determine the extent of unavailability of advertised products. Over a 4-month period, 3,725 products from twenty-three separate newspaper advertisements were checked. Criteria based on FTC substantive policies used in regulating food store practices were developed as benchmark data for this study. The 11.8% average rate o f unavailability found in Syracuse was significantly higher than tlze calculated performance index. Practices found to be significantly related to unavailability were sale period duration, number of items advertised, product type, chain outlet, and whether or not there had been a statement of limited quantities. If future work supports the preliminary findings discussed here, consideration should be given to extending the 1971 Trade Regulation to non-food chain retailers.
