More than a fifth of online supermarket promotions pushed customers towards the purchase of unhealthy snacks MORRISONS nudged online shoppers towards unhealthy snacks more times than any other supermarket in test purchases while Sainsbury’s was most likely to push customers towards alcohol. The first study of its kind in Scotland found online supermarket shoppers are bombarded by around 500 promotions during the average online grocery shop such as multi-buy offers. More than a fifth ( 21%) encouraged shoppers towards snacks that are high in sugar, salt or fat while a tenth were for alcoholic drinks. Sweets,crisps and ice-cream and soft drinks were the ‘discretionary’ items most widely pushed by Waitrose, Tesco, Asda, Iceland, Morrisons and Sainsbury’s.
