Alcohol promotions in Australian supermarket catalogues

The prevalence and magnitude of price promotions in online alcohol retail outlets

INTRODUCTION

We examined the prevalence of price promotions (i.e., proportion of products on price promotion) and the magnitude of price promotions (i.e., size of the price discount compared to the regular price) among online alcohol retailers.

METHODS

In August 2023, we web-scraped product information for all alcoholic beverages available for sale in the online stores of two leading alcohol retailers in Sydney, Australia. Products were classified into five primary alcohol categories: wine, spirits, beer, cider and premix drinks. We considered three types of price promotion: temporary price discounts (e.g., 'was $5 now $4'), multi-buy discounts (e.g., buy one get one free) and 'any six' discounts (e.g., 5% off when purchased in a bundle of any six similar products). The prevalence and mean magnitude of price promotions were estimated overall and by product category and price promotion type.

RESULTS

In total, data for 11,184 products were collected. Of these, 62% were the subject of at least one of the assessed forms of price promotion. The most frequently price-promoted category was wine (91% of products), followed by spirits (35%), premix drinks (30%), cider (28%) and beer (21%). Of all price promotions, 61% were 'any six' discounts, 31% were temporary price discounts, and 7% were multi-buy discounts. Across all price promotions, the mean magnitude of price discount relative to the regular price was 11% and ranged from less than 1% to 71%.

DISCUSSION AND CONCLUSIONS

Policymakers should consider restricting price promotions as part of a suite of strategies to reduce alcohol-related harms.

The frequency and magnitude of price-promoted beverages available for sale in Australian supermarkets

OBJECTIVE

Price promotions are used to influence purchases and represent an important target for obesity prevention policy. However, no long-term contemporary data on the extent and frequency of supermarket price promotions exists. We aimed to evaluate the frequency, magnitude and weekly variation of beverage price promotions available online at two major Australian supermarket chains over 50 weeks.

METHODS

Beverages were categorised into four policy-relevant categories (sugar-sweetened beverages, artificially-sweetened beverages, flavoured milk and 100% juice, milk and water). The proportional contribution of each category to the total number of price proportions, the proportion of price promotions within the available product category, the mean discount, and weekly variation in price promotions were calculated.

RESULTS

For Coles and Woolworths respectively, 26% and 30% of all beverages were price promoted in any given week. Sugar-sweetened beverages made up the greatest proportion of all price promotions (Coles: 46%, Woolworths: 49%). Within each product category, the proportion of sugar-sweetened and artificially-sweetened beverages that were price promoted was similar, higher than the other categories and reasonably constant over time. Diet drinks and sugar-sweetened soft drinks were most heavily discounted (by 29-40%).

CONCLUSIONS

Beverage price promotions are used extensively in Australian supermarkets, undermining efforts to promote healthy population diets. Implications for public health: Policies restricting price promotions on sugar-sweetened beverages are likely to be an important part of strategies to reduce obesity and improve population nutrition.
