CARS, PCS, GROCERIES and now the Internet! Yet again, the UK consumer is the most enthusiastically screwed in Europe, according to a study by market researcher Datamonitor. Despite the launch and massive take-up of so-called 'free'Internet services, Britain's 2.02 million home Internet users are still paying more than their European cousins. Measured in dollars, average monthly subscription costs in the UK top the Euro league table at $25.44 per head, with Germany in second place at $24.14. The European average is $20.00, whilst Scandinavia boasts the lowest costs: Finland, $9.67; Norway, $9.26; Denmark, $8.38; and Sweden, $5.29.
