Occasionally, the vendor(s) run a pre-authorization on the payment method to ensure there are enough available funds prior to packing the items. The pre-authorized amount includes estimated shipping fees and is not the final amount that will be charged. Often, the estimated shipping fees are high to ensure that the final charge will be covered. The pre-authorized amount will remain as ‘Pending’ on your account until the final amount is processed. Depending on your bank, you may see two transactions, but the pre-authorized amount will be removed automatically within 24 ~ 48 hours.
