From where did you get that information?
The UK online purchasing is the largest by value in Europe and went crazy this year, Amazon alone was despatching some 350,000 items every day and all the reports I have read have suggested it way surpassed expectations.
According to Forrester research:
"The largest online retail market is the UK, with 27 million online shoppers spending more than €700 each online during the Christmas shopping season — accounting for a record-breaking €20 billion in online sales. Germany's online shopping spend has grown to €12 billion."
Bear in mind this was forecast in October and was definitely bettered.
