I've just had the regular "We're increasing your bill by £4 a month..." email.
As soon as I get back home I'll call them up, threaten to leave for Sky then sign up for another 12 month deal at favourable terms. Rinse and repeat in 6 months.
I'm on the Large TV with BT Sport and full BB and calls (never used, ever) for £68, although with the month free it worked out at £62 per month.
I keep looking at Sky and alternatives but once I do the sums and read reviews, Virgin has me hook, line and sinker
