I have several packages that I am sending using Media Mail. I have already printed shipping labels for all of them, but when I took them to the post office, the girl said a couple of them weighed more than what I put on them. How can add additional postage to them without having to start all over? I'd hate to have to pay for postage twice. Thanks!!
