I've been following these threads since I bought my early 2009 generation iMac. Returned it in the beginning of September once all the rumors began circulating about this refresh... Anyways, ordered an i7 on October 22 and paid via Visa Debit card. I received an email last Friday instructing me that there was a problem with the payment. Turns out my bank does not allow for charges greater than $1500 as a security measure Called customer service and got a temporary override for the day to cover the full cost of the system $2000+. Logged into apple, resubmitted payment and sure enough the funds were immediately no longer available. On Sunday evening the funds were still there and now "available" again, almost as if the charge had been lifted. This morning I received an email from Apple that my i7 had been shipped. When I checked my bank just now all there is no change in balance and no pending transaction....Doesn't apple usually charge PRIOR to shipping? anyone else have a similiar situation? any thoughts?
