ATG Media's chief operating officer Richard Lewis said: "Much of what ArtTactic have unveiled in the Hiscox survey tallies with our experience of increasing confidence in the online marketplace at the-saleroom.com.
"If you are able to offer what people want, make it easy for them to take part and follow it up with first-class after-service, you will capture a loyal following.
"As technology and our understanding of its potential has developed over the past few years, so have public attitudes and confidence, and many people across all age ranges have a much more sophisticated approach to e-commerce now. We fully expect online sales to continue to expand rapidly."
