I run an e-commerce site, and in my experience what stops people buying across countries is the excessive postage charged (EU to encourage cross-border e-commerce, www.computing.co.uk/2219738).

At the moment it is many times more expensive for us to ship from the UK to Europe. Were it not for this, we would put more energy into translating our sites and accepting the euro, and marketing in mainland Europe.

As it is, the postage makes it too expensive for people to buy from us.
