My Mum has 5 variety mixes with a standard box at the moment but would like to upgrade to Sky+ keeping the same mixes, getting there broadband (base) and getting there phone package (unlimited).

Can anyone tell me the best way to go about this?
I've checked online and the price seems to be 99 for sky+ box and 60 instalation fee.
This seems a bit dear seeing as she want to get everything from them and so will be paying them a lot more money every month.
Any help would be great.
