I have an order that was scheduled to be delivered on the 9th according to the USPS track and confirm. It's not here yet and I've e-mailed the vendor. Should I let them check into it with the post office, or should I try contacting the correct dept. in the post office and try to find out what's going on. All the track and confirm shows is that the package passed thru the sort facility from where it was mailed from on the 7th. I'll wait till Monday the 13th before I really start to get concernd,but just wondering who should do what here.
