be careful with this offer because if you have any other offer on your account it won't work out at a pound.

Basically what they are offering you is the 3 4 30 deal with the free upgrade to tv xl for a year. Because the telephone and BBI work out at £29 thats why they are saying its only a pound.

The upgrade offer has now ended so you would not be able to get this anymore, but you could still get it with the L tv package.
