Just doing my random check on when gold expires on my profiles and I realised one was silver. Checked the dashboard and was greeted with this offer.
Image is taken by myself, with an Australian Xbox LIVE profile, on the Xbox LIVE dashboard.
As always, read the terms and conditions before committing to anything on Xbox LIVE. This requires a valid credit card and removing that information is like trying to get an engagement ring back from your ex fiancée.
No way of doing it without giving them your CC? :(
I only have a couple of days left on my gold subscription.
