I ran into this with Secret Santa :hunf: I had used a box from work, not a Post office box, nothing priority in it, on it or around it. Took it into the local Post Office... the clerk started to rip the box open, asking "Is this a priority box turned inside out ?" when she saw that it wasn't and I told her NO , she tells me well the box is partially opened now, you need to retape it .. uuhh HUH? Do I look like I carry a tape gun in my back pocket ? :hunf: :hunf: I paid for the shipping and left.. My person received it and I did not retape it
