European shoppers are having trouble embracing e-commerce stemming from problems when buying from foreign sites, according to Britain's Channel 4.

Six percent of European consumers purchase from sites outside their own countries. And one-third of shoppers had their business refused by the e-tailer when attempting to buy.

Pre-internet laws designed to regulate cross-border commerce may be at the source of the problem. The E.U. said it hasn't yet developed a strategy to resolve the problem.
