U.S. consumers are also behind when it comes to online shopping tactics: They are much less aggressive when hunting bargains, with U.K. consumers eight times more likely to conduct research on multiple sites before making an online purchase.

Interestingly, neither U.K. nor U.S. online consumers seem ready to embrace their cell phones as shopping devices. Only 10.2% of U.S. and 10.4% of U.K. consumers agreed with the statement, "I would like to be able to shop and make purchases on my mobile/cellphone."
