Shoota - do what I did - ring them and tell them you're moving 'cos you can get an introductory offer from Sky, etc.
I did this and lo and behold, they started telling me about the offers that they have. Apparently you have to ring and ask - it's a case of, if you don't ask, you don't get.
I was paying approx £40 per month for phone, 20MB broadband and basic TV - with a normal Virgin Box.
The Virgin engineer has just left my house about an hour ago and I've been upgraded to 30MB broadband, with a Tivo box ..... and I'll be paying slightly less - approx £37 per month.
