I will also send any added postage if you get mine and it says postage due. Please let me know. I was going to us my scale at home, but I may just do it at the post office. I can compare and see what happens. I will weigh here and see what I get when I go to the post office tomorrow. Will see what happens.
I did notice that if I use a ziploc bag it is more money, if I wrap with saran wrap it is less postage.
