I have done 5 of these without any issues. Today I actually mailed something that needed to be shipped. I checked the weight at home before going to the PO and I was right at 18 ounces. Tonight I start to put in my data and I look at my receipt and I came up an ounce short at the PO. Do I go forward with the report? Do I just e-mail the scheduler? Everything was fine on the shop. The clerk with through the usual stuff, even without me being at the exact trigger weight of 18 ounces. Bad part is this shop was 30 miles from where I live. I combined it with several more shops I had in that town. I'm totally bummed. Just trying to decide if I even bother entering the report. Thanks for the advice!
