Its still not ringing true though, because Tiscalli are being charged about 85-89p per customer, so I'm assuming that is a per month figure per customer, which means that the so-called VM figure of 3p per day, 90p per month is way over the odds given that VM have a much larger customer base.

I'm not doubting your source, but as more figures come out about other deals with other companies, it appears more to the point that Sky were not interested in securing a deal, they simply wanted to poach VM's customers.
