I remember a few years back mailing a rather large box up north to my daughter. I mailed it regular parcel post ($25) because 2 day was $50. I waited over a week and she never got it. I called the PO and they didn't know where it was and it should be there in a few days.I went to the PO a few times also. It took over a month to get there and never even left the PO until a few days before getting there. It was a LARGE box, I don't know how anyone could have missed it. My brother in law works at the PO it had to go thru, so he was watching for it. It arrived in rough shape.I was really aggravated
