. But not as much as you thought.
I see they now do 250GB and 350GB at an extra £10pm each. (That extra 50GB only from 1 Dec of course). Base price now complicated by including the £10 raw DSL line rental so now we have to mentally subtract it. (Thank you Ofcom/ASA. Not!)
One of those might be worth considering for you?
