In today's mail, I received a copy of a book I had requested April 11.  The member said she mailed it April 13.

May 9, I still had not received it and PBS cancelled saying lost in mail.

I ordered the title from someone else May 20 (after waiting even longer as PBS said to do).  I received it and read it.

Lo and behold, the title arrived today from the person who said she mailed it April 13.  She did NOT do so.  The postmark is clear.  It was mailed June 2.

I do not feel I should have to give a credit up for the book.  I do not want 2 copies and the member knew that PBS cancelled the order May 9 and still waited a month, did not send PM, etc.

What do I do now?

Sit tight.....you do not have to spend 2 credits for the same book.  If she wants the book back so she can repost it, she must friend you a credit to cover the postage to have you send it back to her.

• • • The bottom line: If a sender sends a book late without getting confirmation from you that you have not gotten or requested another copy in the meantime, and you end up with two copies of the book, the sender has made the mistake here.  In this case (and ONLY in this case) you are not obligated to mark the lost book received (nor are you obligated to return the extra copy).
  • You should also contact us to let us know about the extreme late mailing, so that this can be noted on the sender's account.

Thanks for the helpful responses.  I am very relieved!  I did send information through contact us as well.

The second sender should get the credit for the second book. The first sender is required to get a PM okay from you for any book mailed over 4 days late. Over a month late? No.

The second sender did get the credit the day it was received.

From the PBS Help Center:

• If the book was declared lost in the mail and you requested and received (or will receive) a second copy because you thought the first one was really lost:
  • If the postmark on the package was from the week before the book was declared lost (or later!), and you got no notification from the sender that the book would be/was mailed late: you do not have to mark this book received (this is the ONE case in which you don't have to mark a received book received: if a very late mailer without notice caused you to reorder the book and end up with two copies).  
  • OR: You can mark it received to note the late postmark, and ask for your credit back in your Personal Message to the sender.  If you don't hear back/don't get the credit back within 3 days you should contact us using the Feedback link at the top of the Contact Us page.
  • You can also note this information about the late mailing in the Comments box at the bottom of the Book Received page, while marking the book received: this will go onto the sender's record.
