Our system will not know a shipping charge until the product is actually shipped out. So it will estimate what shipping is, usually this is higher than what the actual charge is and what we tell you on the phone. So it will add that higher shipping fee to the cost of the part and do a pre-authorization on your card for that amount. After the product ships out, the charge will disappear and the correct amount of freight will be added to the cost of the part for your final total. This new amount should be less than the original amount you were charged.
