Online purchasing in the UK has doubled in the last 12 months.
Since January, the number of Internet consumers has risen from 2.3 million (5.1% of the population) to 4.7 million (10.7% of the population) according to a report for Experian.
The report, which surveyed over 500,000 Internet users, reveals an increase in repeat purchases: consumers buying more than four times online rose from 24% to 31%.
Shopping online is most frequently used by the young and the wealthy: the 18-25 age bracket is more that twice the national average, while the 26-35 age group are at almost 166% of the national norm.
The over-55s - labelled silver surfers - are showing a significant number of online purchases, making up 20% of all online purchasers.
The most popular product is still books, but holidays and music are increasing in popularity. Financial (previously 4%) and health (3%) products have both fallen to 1% of online purchases.
"This may be due to the security issue of providing personal data on an application form on the Internet," said an Experian spokesman.
