Premier Sports are also increasing their prices:

Premier Sports is currently £9.99 per month on Sky, Virgin TV and the Premier Player. Please note if you are a Premier Sports Sky platform customer you can access the Premier Player for free.
From July 8th, the subscription price will increase to £11.99 monthly for new customers to Premier Sports on Sky or the Premier Player.
Reading this, it looks like Premier Sports won't be increasing for new customers on VM!? Is this correct?
