I meant to add, i sent 2 boxes to the same address to see which box got there faster. 1 i did the regular way, the other i put delivery confirmation on. the one with the DC got there faster, i called the PO and asked why, their reply was, no box is guaranteed, i said we are to have the boxes in 2 -3 days for priority mail. she said it's not guaranteed, i told her that's BS we pay for that, so now i do DC on my pkgs.. :rolleyes2
