Online sales have grown 16.6% since last year, figures from the British Retail Consortium showed today.
Sales fell in the days after the recent banking crisis, as consumers became anxious about their finances, but overall growth for the year was significant.
Online sales account for 4% of overall sales, and are included in the final figure.
Sharon Hardiman, head of non-store retailing at the BRC, said, "The internet relates to a relatively small, though rapidly growing part of overall sales.
"Growth here reflects the increasing importance of the multi-channel arms of existing in-store retailers."
