Was just looking at the billing preferences page and came across a section called "Backup Payment Details" which allows you to submit additional credit card details.
I am assuming this kicks in should the primary card fail for some reason.
If so, what a great tool.
sorry if I am late to the party with this news, kinda out of the loop these days.

Of course the one time I had to switch over, it didn't go too smoothly. Google did 10 authorizations in 2 minutes to the secondary card and the card processor put a "hold" on the account suspecting fraud!
