Adapting to different currencies, languages, and shipping destinations isn't free for the shops. But many do support selling to other countries.

If the EU bureaucrats really wanted to look out for consumer interests they should make member countries abolish all tariffs on products coming from non-EU countries.

It says "Europe" at the header of that Techcrunch page but has en EU icon next to it. Europe!=EU

The irony is that the people running these businesses probably are very aware of that potential, since they likely scour the european market for the cheapest supplier for the business. Yet they're, for some reason, too short-sighted to realise that they need to pass the 'globalism' on to their customers as well.

And I'm sure they'd complain loudly if they ran into a cheap supplier that refused to ship outside of their national border.

for small items, such as CD's, the cost of shipping across borders in Europe is prohibitive. So why would a retailer offer cross border shipping?

In many cases I can buy a CD in States and ship it to the UK cheaper then getting it from Scandinavia.

Then again if shipping volumes increased in Europe then costs may fall.
