USPS…….HOW MUCH?

I've had them give me that line of crap before, the only difference was I HAD the estimate receipt WITH the measurements on it. The clerk was so argumentative I had to call the postmaster out of her office (who I know), tell her what was going on and she sold me the correct postage. There are so many people working for the USPS that know absolutely nothing about their jobs or even care it's pathetic.
