I think you're on the old VIP package because VIP now includes 100/120mb broadband and Sky Sports and movies in HD, if you change to the new VIP 'collection' you will get all the stuff new customers get for £114.98 but you might even be able to get the half price for 6 months offer too. Just give them a ring
