Received this pm just now

"I mailed this book World According to Bertie (44 Scotland Street, Bk 4) by Alexander McCall Smith but neglected to mark it mailed before the deadline, and it was canceled. If you have an active request on your account page for World According to Bertie (44 Scotland Street, Bk 4) by Alexander McCall Smith it is not with me--it is with a new sender. Your request must have been passed on to that person, and you will get 2 copies of this book if the new request is not canceled. If you do have an active request on your account page for this book can you cancel it? You will be getting a copy of the book from me. You can then mark my book received when it arrives, from your Transaction Archive. If you are willing to do this I really appreciate it! Just let me know if you have a new transaction on your account page, and if you are able/willing to cancel. I am very sorry about the inconvenience. I am going to mark my books mailed before the deadline from now on! I was on my cell phone and thought I had marked it sent but apparently that wasn't the case."

It has been passed on to the next sender and they have accepted and printed it but not marked mailed. I'm not going to pay 2 credits for 2 copies of the same book but I will have to mark the first one recieved when it comes. What is the procedure here?

You do not need to do anything regarding the cancelled request, she is out the book and the credit.  You should mark the second book received when you receive it.  She did the right thing by emailing you what she did, but because it is too late for you to cancel the active transaction, the help docs tell her she is out of luck.

From the help docs for you:

Scenario #1 (the most common scenario):

• You submit a request, which goes to Sender #1

• Sender #1 does not mark the book mailed before the deadline, but still mails the book.

• Then the request cancels and gets passed to Sender #2, who also sends the book.

• You end up with two copies.

  This situation (the requestor ending up with 2 copies of the book) is part of why marking a book mailed before the deadline is such an important part of the swapping process.

  The bottom line here: always mark your books mailed, so you don't become Sender #1!

Scenario #2:

• You submit a request, which goes to Sender #1

• Sender #1 clicks  on the transaction by mistake after (or before) mailing the book.
• When she does that, the request cancels and gets passed to Sender #2, who also sends the book.

• You end up with two copies.

In both Scenarios #1 and #2: When you receive 2 copies for a book after submitting only one request, you are not obligated to give a credit for the extra (canceled) copy.  You are obligated to mark the properly sent copy received.

• When you mark the book received from the active transaction on your En Route to Me tab on your My Account page, Sender #2 will get credit. 

• • Sender #2's transaction is the only active transaction for the book on your account page.
  • The transaction with Sender #1 moved into your Transaction Archive when it was canceled, as a canceled transaction.

• You are not obligated to give a second credit for a canceled copy of a book when you submitted only one request
  • You are also not obligated to send the canceled book back (although this is a nice thing to do if the sender is a new member).
  • You are obligated to mark the book received that is on your En Route to Me tab on My Account.
    • You should NOT refuse this copy of the book or mark it "return to sender" - doing so will cause Sender #2 to have to pay postage again to claim the book.

Yeah, since the second sender already printed the label (and possibly postage) they would be the one to receive the credit when their book arrives, unless you want to contact them and see if they'd be able to cancel. An unfortunate slip-up for the first person, but the second sender had nothing to do with it and should not be penalized for someone else's mistake.

So it doesn't take a second credit when I mark the 1st late mailed book received? That's the only part I wasn't sure about.

If you receive the second copy, you don't have to mark the first one as received.

So it doesn't take a second credit when I mark the 1st late mailed book received? That's the only part I wasn't sure about.

In order to mark the first senders book received, you would have to go into the Transaction Archive and mark the book received from there. If you do that, it WILL take a second credit for the book.

So, don't do that.  When you get the package from the first sender, don't do anything. When you get the package from the second sender, mark it received how you woudl normally.

This is one case where you do not have to mark the first book received. The sender screwed up, and by the time you got the PM, it was to late to fix the situation on your end. The first sender is just out of luck.

So, send her a PM, saying that although you would have liked to help her out, it is too late to cancel the second book order because the label was already printed.

It has been passed on to the next sender and they have accepted and printed it but not marked mailed.

You can try sending a PM to the second member to see if the Transaction can be cancelled yet. Because it has been printed it gets more complicated, you can't cancel and they wouldn't want to and lose their place in the FIFO line. If they were willing to cancel (no postage paid) they could contact the Team (via the Contact Us link and using Feedback) and tell them the situation and the Team could cancel the transaction. Then when the first book arrived, you could credit them by marking it received from your Transaction Archive.

But if you receive 2 copies, you are only obligated to mark the second one (the one was properly marked mailed and is on your main My Account page) as received. If you search the HelpCenter Documents for * I received two copies* you will find detailed information on the situation. 

Right after I first joined, I ended up getting two copies of the same book because the first sender didn't mark the book sent.  The way I handled it was to let the first sender (who forgot to mark the book mailed) know that if she was interested in any of the books on my shelf and she ordered one directly from my bookshelf, I'd be happy to include the book she sent to me and forgot to mark mailed with her order.  That worked for her--it probably cost me just a little bit more postage to mail two books instead of one, but she got her book back and hopefully another book that she hadn't read yet.

I agree with Melanie, you could attempt to catch the 2nd sender if you like.  If they have purchased postage it may be too late for a refund, but it they are agreeable and catch it quick then PBS admin can cancel the 2nd request and refund the costs (if any).

If the second sender is going to be out any postage/DC costs, then do not ask her to cancel...in this case the first sender will be penalized for her error, so do not mark her book received when it arrives.

Great minds think alike Laura, lol. I looked at her WL earlier just in case, I didn't have any of the exact books on it but I do have several by the same author on my TBR pile. We have surprisingly similar taste in books. So I sent her a pm saying if she was interested I would send her a copy of my TBR pile and if she saw anything she liked I'd read it and post to her including the extra book. 

I didn't see a way to look at other people's TBR piles, if there is and I missed someone please let me know.
