Research has found that supermarkets have boosted their special offers to a record high of 12,000. Tracking of online prices at Tesco, Ocado, Asda and Sainsbury's has shown that customers are spending more time browsing deals online to save money on grocery bills. An average 41 per cent of goods in a typical customer's trolley are bought on promotion, up from just 32 per cent in January 2009. British Retail Consortium food director Andrew Opie said the record number of special offers now available showed shoppers were benefiting from fierce competition between stores.
