Hello guys & girls after a little advice please,

Basically my Corsa vxr is due a main service and I was wondering what sort of price I should be paying first of all and if the masterfit service club card will actually give me 25% off ? I mean the fixed service price says it'll be £200 so with discount that'll make it only £150 ish?

Also the service club card I have has my dads reg on it as they wouldn't allow us to each have our own? Will this mean I can't use it?

And finally are wiper blades included as mine are starting to go ?

Any helps appreciated sorry for such a noobie question this is my first year of ownership,
