Feh. I can't buy anything from iTunes on my computer. I keep getting a "your card was declined" message, even if I try using Paypal, or another card. My wife can use the same card to buy from her iTunes on her computer. I am able to buy things from my iPod touch using any card or Paypal, same iTunes account..... I called my credit union and the card is fine, they show a bunch of $1 authorizations where iTunes verified the info, and no declines (meaning that it is likely an iTunes problem not a card problem). I also just used the card to buy lunch.

Windows XP SP2, iTunes 9.1.1.12 (updated this morning)

I see from the googles that other people have had this problem, but I can't seem to find out how they fixed it. Yes, I emailed iTunes support, but I don't really hold out much hope for help.

So.... ideas?
