Women turn to online shopping

Women have jumped ahead of men for the first time in using the Internet to do their holiday shopping,according to a study published last week in the US.

For years men have been more likely to shop on the Internet than women,but during the 2004 holiday season 58 percent of those making online purchases were women.

“It shows how mainstream the Internet is becoming”,said Lee Rainie,a director of the Pew Internet and American Life Project group,which carried out the study.

Rainie said it was only a matter of time before women shoppers caught up with men. This is because women traditionally make decisions about spending.

Users were more likely to shop online to save time. Internet users between the ages of 18 and 29 were responsible for some of the most dramatic(显著的)increases in the online gift-buying population this time around.

However,three-quarters of the US Internet users did not buy holiday gifts online in 2004.They worried about credit card security,or just compared online prices with off-line prices,then dashed off to the shops to get the best deals.

“But even if shoppers don’t buy online,websites are becoming promotion tools for stores,”said Dan Hess,vice president of Comscore Networks Inc.Hess said that actually most stores’ websites can make shoppers fully believe the security of their credit card numbers. And most are able to ensure that gifts arrive on time.

“It’s all about making the shopping experience more efficient,more reliable and more comfortable,” Hess said.
