I am just curious about this scenario. I got my credit a while ago for it.

I mailed a book. I used PBS DC. It was delivered on 8/25. The sender has yet to mark it received, and didn't respond to the PM I sent her on 8/30.

I realize she might be out of town, or sick, or whatever.

BUT...what happens on 9/13 (the PBS date of action) if she has not marked it as received? I know that a book can go "lost", but what about a DC book?

Here is what the help says about this:

If you sent the book with PBS-DC and it has been recorded as delivered by USPS but hasn't been marked received yet:

• Remember that the book could have been scanned as "delivered" at the local PO, before it went to the requestor's mailbox--the actual delivery can be a few days later  Also, the book could have been misdelivered.
• You can contact the requestor using the button on the transaction on the Books I've Mailed tab in My Account when a few days have passed after delivery.
• If the requestor does not respond to your PM within a few days, and/or has not marked the book received by a week after the delivery scan, contact us.  We will look into it.
• You will already have gotten your credit when the barcode was scanned by USPS. 

thanks, Anne. I can never find what I'm looking for in the help center!
