The research showed that around two thirds of shoppers spent more online at Christmas and a third of shoppers did more than half of their Christmas shopping online.
Capgemini UK head of consulting Mike Petevinos said: “This is the first recession we have seen where online will play a significant role in mainstream spending. Our research provides further evidence that consumers are turning to the internet as the most efficient way to save money in the downturn”
