Sorry, I tried to hide enough details of the package so no one would know where it came from, and keep it to a general discussion of the subject. But now that you've "outed yourself" I say again that I'm not upset with you, and that you are one of the good guys. It would be hard to go to the Post Office and tell the window clerk "I want to pay more for the package than what you just charged me". Might have to get to that though, if too many buyers send notes back to you about postage due.
