FYI - USPS is taking longer than usual to get packages to their destinations, and if you sent with tracking, that may or may not be helpful as it would seem items are not being scanned in and out of sort facilities.
I have two packages out there that are taking way longer than they should, both priority. First package ship Saturday the 12th, delayed leaving our PO due to bad roads, finally left on Monday, scanned in and out of local PO and the main state facility and then nothing. Predicted delivery was Thursday the 17th, finally an update today, it's one state away from it's destination with expected delivery of Monday. Second package shipped Wednesday the 16th, only scanned in and out of local PO, scheduled delivery of today, only scan was early this morning, it's arrived in the right state, but I don't know if delivery is on time or not (recipient will let me know, so that is good). Three more packages in today's mail, we'll see what happens with them, but there won't be any tracking til later today at the earliest; only one is Christmas package, so hope it arrives on time.
