"A competitive European economy needs consumers who are willing to shop across national borders. This poll confirms the need to continue to strengthen the EU's consumer policy," said Health and Consumer Protection Commissioner David Byrne.
Overall, respondents' opinions on the impact of the Single European Market were positive, especially as regards choice.
Opinions about its impact on prices were less positive. Only 15% of EU consumers say the introduction of the Euro made them more interested in cross-border shopping.
