not sure why taking money out of the account account would mean it shipped.
the purchase price when charged can either be a hold or a completed transaction, both puts a hold on those funds. the company then has, I think 7 days to request those funds else the hold is removed and the money is then refunded to the account.
What you have to be careful of, especially with a debit card is apple can run another charge through for the same amount to complete the transaction.
meaning you could have 2 holds or a completed charge and a hold on your account for a single purchase.
