Why is my credit card preauthorized for more than my order confirmation amount?

When an order is submitted our system issues a preauthorization on the credit card. As standard business practices the preauthorization is a percentage higher to account for taxes or freight charges that may apply when the order actually ships. The preauthorization will drop off the account once the card is charged for the actual invoice amounts.
