Thanks guys, I had a hunch he meant that. I'm going to try and clear this up at the post office tomorrow when I go, I would love to understand their system better in order to get the cheapest option. A few times I wrapped a shoebox nice and neat in brown packing paper thinking it will be the cheapest and then when I get there its even more than large flat rate and I have to rip it all open and repack it in a large flat rate box. Did they stop giving packing tape for priority shipping by you guys too? Wonder if they will start charging for the boxes soon.
Why not print the label at home? You can see all the options and pricing right on your screen to make the best choice. Plus shipping is cheaper online.
