Aren’t Websites Supposed to Save Money?

This includes £4M spent on developing the UK Trade and Investment website alone — a site that averages 28,000 visitors a month.

Hopefully some of those visits resulted in sizable investments in the UK economy, because I can’t begin to understand how so much money could be spent on a single website.
