Concordance of Advertised Cigarette Prices with Purchase Receipts in the United States
Objectives: Researchers and regulators study the advertised price of tobacco products to evaluate compliance with minimum price policies, tax increases, and geodemographic marketing. However, few studies report reliability of advertised price and none address its concordance with receipt price. Methods: In a sample of US tobacco retailers (N = 1972), data collectors purchased the leading brands of non-menthol and menthol cigarettes, recorded advertised prices, whether sales tax was included, and whether price was discounted. Intraclass correlation coefficients (ICCs) were computed for the same measures by different observers (reliability), and for receipt and advertised pack price (validity). Discrepancy between receipt and advertised price was modeled as a function of store type and presence of a discount. Results: Advertised price was assessed reliably (ICCs = 0.74 to 0.87) and concordance with receipt price was near perfect (ICCs = 0.96 to 1.00). Advertised and receipt prices were identical in 77.7% of stores for Marlboro and 78.1% for Newport. Differences between prices were related to store type and presence of a discount for Marlboro, but not for Newport. Conclusions: Findings validate a common measure of cigarette price in research on minimum price compliance, effects of tax increase, and industry marketing.

More about this publication?
- Tobacco Regulatory Science (Electronic ISSN 2333-9748) is a rigorously peer-reviewed online scientific journal for the dissemination of research relevant to the regulation of tobacco products. The journal content includes a broad array of research domains, including chemistry, biology, behavior, community, and population-level surveillance and epidemiology, as well as knowledge syntheses (eg, meta-analyses or state-of-the-art reviews) and analytic modeling. All articles describe the policy relevance of the research outcomes. Given the global nature of tobacco regulation, particularly as a result of international and national policies, Tobacco Regulatory Science publishes high quality research that is relevant to global regulatory needs and requirements. Tobacco Regulatory Science is published electronically 6 times per year.
