I just went to the Apple Store the other day to get a Mini Duo and my credit card was short, so I ran to my bank but it was closed. Then I told them, I'd get a Solo and they rung that up and I couldn't get it because the CC wouldn't go thru. I can certainly attest to your pain, but now when my card clears I will get the Duo that I wanted. It has been 2 days, and still the credit card hasn't taken the charge off. The manager at the Apple Store said it could be 3-4 days.
