My missus has set up her credit card details on the youngsters XBox to pay for his ‘Gold’ membership
I can’t see a way of removing the card details & a subsequent Google search seems to confirm it can’t be deleted – not too worried but ……..

Does that me him & his mates could spend an afternoon in his room buying stuff via Xbox Live?
i.e. does it ask for details again if he tries to buy something?

He could buy microsoft points to buy arcade games and premium content.

There are parental controls that you can use that require a password to download stuff to stop him going on a spree.

Change the details to a made up card it will forget the old one.

I’ll try both those thanks

My son wanted me to do this but I was not happy about it so I got a scratchcard type membership for one year from zavvi and only paid £27 for it

I would have done that too but she went off & did it – she doesn’t seem concerned though.
