"Three
huge boxes of Pampers cost € 168 on Amazon’s Spanish website. On the other hand, the same
order on the British Amazon site costs only 74 €...The EU may have a single market,
but its products do not have single prices. In an integrated market, prices are expected to move
closer over time. Yet this process has stalled EU. Prices for
exactly the same products still diverge, often greatly and even among rich
countries. This is a long-term trend: prices stopped moving together in 2008..."America is much more
integrated, sigh EU officials. As a result, large online
retailers like Amazon are offering a buyer in Alabama the same price as a buyer
in California...Sometimes pricey Pampers as as important as high politics"

PS - Also intriguing in this edition of The Economist
is the article about UK obsession with Germany with phrases such as: "todays surge of enthusiasm for the Teutonic model is striking...learning German lessons demands a
seriousness that British politics lacks...learning from another culture is
difficult under any circumstances, but it is hard to think of a government that
is less equipped for a Teutonic transplant than the current one"
