I got an email a few weeks ago from a fellow trader who was mad at me because he had to drive to the post office, wait in line and then pay the $.55 postage due on the package I sent him. I had to inform him that if he looked at the postage on it he would see that it was applied by the Postmaster in my city and I had nothing to do with how much postage was on it. I complain every time I am at the post office (including today when they charged me $17 for postage) about their stupid rate schedule. It now costs over three times as much to send a one ounce package as it does a one ounce letter. And even they don't know what the standards are for the fuzzy description of "rigid" or "flat". Sheesh!
