The iTunes Store is unable to process purchases at this time.

I’ve been trying to give Apple my money all weekend and all I keep getting is an error that says “The iTunes Store is unable to process purchases at this time.  Credit card processesing is temporarily unavailable.  You may continue to browse the store.  Please try to make your purchase later.”Well, I’ve been trying for over 24 hours with little success.  At first I thought it might me a problem with PayPal, so I switched my payment method to a Visa checkcard.  That let me make one $3 purchase and then it too gave me the credit card error.  I’ve been checking the Apple Discussion Boards and the problem is occuring with all forms of payment, even gift cards.If you’ve been having this problem, chime in with a comment.
