Of n=8679 cigarette smokers, we excluded those who: did not provide their current brand name (n=283); currently smoked unbranded tobacco or gave a brand of cigars/cigarillos or e-cigarettes (n=60); did not recall where they purchased their pack or received it as a gift (n=75); did not provide a valid pack size (n=231); did not report a price (n=413); purchased tobacco duty free or overseas (n=70); skipped relevant questions due to back-coding of verbatim responses (n=77); gave responses that were deemed unlikely to be correct (such as a non-existent pack size or unrealistically low or high price) (n=243); or did not have socioeconomic status information (n=151). Analysed n=7076.
