Trying to place an order for a 12" powerbook + airport extreme card in the Apple UK Educational store. I enter in correct VISA debit card details, expiry date etc. (100% sure), but it says something like "we could not authorise taking the funds from your bank. please try another card" ...great... i don't have another card This card has worked countless times before on various shops (including apple's store last year), but isn't now The account definately has enough money in it. What i'm wondering about is this - from another online computer store, dabs.com: Apple didn't ask for this number, only an "issue number, if applicable" which I don't have and is only 2 digits anyway. Does anyone know why, or have any hints?
