I ordered a book about 3 weeks ago that I haven't gotten yet.  The sender used DC though, and the last barcode scan says "arrival at unit".  I asked my mail carrier about it and he had no idea.  Is there anything else I need to be doing about this?  Oddly,  I keep getting these e-mails from PBS asking if I've gotten the book but the sender hasn't said anything.

ETA: this is what the PBS details say:

8/23/2009 11:00 PM - Electronic Shipping Info Received - sender's town

8/26/2009 10:07 PM - Enroute - intermediate town

8/27/2009 4:40 AM - Arrival at Unit - my town

8/27/2009 10:14 AM - Arrival at Unit - my town

Have you tried contacting your main post office directly?  I would give them the DC or stop by during a non-busy time with the information and have them look for it.

You can call the post office that handles your mail.  Sometimes the books are still there even though they have been scanned as arrived.  After all, your carrier probably does not get paid for the extra time searching the building for a lost book.  Makes little motivation to look for it.  The other employees are usually paid hourly, unlike the carriers.

I know I'm not worried about arrival times for books I've sent with DC.  I've already got the credit.  Now the ones without DC....

Arrival at unit usually means it's at your local post office; it might be sitting in the back room somewhere, being all lonely. :D  I would go down there or at least call your local PO to inquire, depending on the size of your PO and the number of carriers working out of it, he may have no idea where it could be.

After two weeks, I would definately copy the DC number and call or visit my local post office (unit).

I think that Arrival at Unit means it's at the distribution center.  I've had books arrive and say that - Arrive at Unit but for me that is not my local PO.  For me that's actually quite a distance from where I live.  I've sent a couple where it's Arrived at Unit and that will be a different city/town name than where I sent it.

I think Cheryl's right that the package is sitting on a shelf getting lonely.

and lots of people do not pm about books they have sent not being recieved yet. 

PBS has automated emails that they send in case you have recieved it but forgot to mark it.  The email would remind you and you would then mark it.  No need for the sender to do it, when PBS does it automatically.
