An average weekly spend of £727.5 million was recorded, which accounted for 11.4 per cent of total retail trade with the exception of automotive fuel. This is up from 10.3 per cent in May 2013.
The biggest increase in online spending occurred at department stores, where growth of 26.5 per cent was recorded. Internet-based trade now accounts for 10.5 per cent of all business in this sector.
