All models adjusted for store type and area SES.
*Store type excluded from logistic regression analysis as brands from ‘other’ manufacturers were never observed as the top-listed product in small mixed businesses, newsagent/lottery outlets and tobacconists.
†Store type excluded from logistic regression analysis as multibuys were never observed in small-mixed business and only once in each of convenience stores, newsagent/lottery outlets and tobacconists.
‡SES excluded from logistic regression analysis as packs of 30s were never observed in stores in high-SES areas.
§Store type excluded from logistic regression analysis as packs of 40s or 50s were never observed in convenience stores, and rarely in newsagent/lottery outlets (twice) and tobacconists (once).
