I had a Alert from Audible that my card wouldn't go through for my monthly membership.
I immediately thought it had to do with the Target fiasco. It turns out somehow the billing address changed for my card.
I have no clue how that happened. It worked last month and earlier this month fine. So my guess is there was glitch in the system so if you get a notice like that don't panic check your Card's billing address.
I had thought the cards were linked to Amazon's account but maybe they are not now because the billing address there was correct but not at Audible so maybe something has change since last month?
