Got an email from Apple, says that they not able to obtain an authorization on the credit card.
I ordered 2 items, the cuztomized mbp not yet shipped and ipad camera connection kit has been shipped yesterday, so I thought there will be no problem for my purchase, but now...
it's so shocked when I read the mail O.O Oh mbp my pity mbp I wish to get it on time T_T

Got a call from card centre to get approval for that transaction
shouldn't have any problem now, finally i can wait for it peacefully
