Consumers' lack of confidence in online security is hindering internet shopping, according to new research.
The National Consumer Council (NCC) said shoppers were reluctant to release credit card and personal details online.
They were also wary about the lack of opportunity to check goods before buying.
These fears were compounded by widespread ignorance of legal rights and redress for consumers when things go wrong, the council said.
NCC Director Anna Bradley said: "It is especially worrying that internet users are more, not less, likely to harbour doubts about shopping online.
"For instance, almost four out of ten adults see the need to release credit card details as a major disadvantage of internet shopping."
"Among internet users, more than half feel the same way.
"This heightened awareness is evident across the board from delivery problems and not being able to touch goods to releasing personal information."
