Switching from Virgin to Sky

Hi everyone

Ive been with Virgin for over 3 years now and ive decided to switch to sky as i think virgin isnt great value for money. They have so far only offered me a poor deal to try to keep my custom.
I was wondering if anyone knew of any discount codes around at the moment?
Think i would take up entertainment and sky sports and unlimited bb. If anyone can point me in the right direction I would be most grateful ;)
