Last week I received the wrong book.  I PM'd the sender to let her know and she got back to me tonight telling me the other person has now received the book I requested. She just put the wrong addresses on the packages (mine was handwritten). 

She gave me the PBS name of the other individual and said she was sorry we were going to be out the postage to exchange these books, but accidents happen. 

So I wrote back to her and let her know about buddying credits in a situation like this and that the lady that has my book apparently has no profile set up, so I couldn't find her in the members directory. 

I haven't heard back from her yet. 

I don't know about the other book, but the one I requested hasn't gone lost yet, and it will be another week and a half or so before it does.  There aren't any other copies posted right now. 

What would you do?  How long would you wait to hear back?  Is there anything else I can do to try to contact the lady who wants the book I received? 

This will probably all be moot tomorrow if she PMs back and says "Oops!  Sorry!" and takes care of it.  :-)

I would politely point out the help document titled "I sent a book to the wrong person!" specifically the section where it says:

• If you mixed up two requests:

• Each requestor can send the book to the other
• You should offer credit or postage to each of them, and provide the addresses in PMs.

Whatever you do, do not mark the book as received.  You'll get your credit back when the book goes lost.  She probably doesn't realize this.  If you can't find the other person then there's not much else you can do. If this was the only copy, you could put the book on your WL.  If the other person doesn't try to find you, they might just post the book.  If you're the only one on WL it'll get offered to you.  Then you just use the credit you got back for the lost book to order the right one.  If it's the same person, PM them and tell them you got their book and ask if they want you to post it so they can order it from you.  If you mark the book RWP and select received wrong book-you will not get your credit back unless she returns it to you.

It's ok to let the book go lost since you haven't received the book.  I was told to do this when I got the wrong book recently. Fortunately, the sender refunded credits to both of us and she had put the right packing slips with the books, just swapped the wrappers.  So I had the other person's address and they had mine.

You do not have to send the book back to her unless she gives you 2 credits: One to cover the book you didn't get and one to cover the postage. 

I would also suggest reporting her to PBS.  Yes mistakes happen. But part of being a grownup is taking responsibility for your mistakes and making up for them. Which in this instance means refunding credits to cover the extra postage costs.  By refusing to do this she is not following PBS rules.

No way would I send the book to the other person unless I got a credit for the postage or the $$ to cover the postage.

If she doesn't get back to you, just let the book go lost, you didn't get it so you don't have to mark it as received.  Maybe the sender will do something when she's out credits for mixing up these books.  Hopefully the other person lets her book go lost also.

I'd give it until the book goes lost and see if the sender does something then.  If not, I'd repost the book I received and WL the one I wanted but didn't get in case the other person posts the incorrect book they got.

I heard from her this afternoon.  She doesn't sound happy, and we're still trying to get me together with the other lady, but there's progress!  The books will most likely go lost before this thing is resolved, but that's okay.  I know what to do about that.  :-)  Thanks! 

I did this myself...it was quite embarrassing!  I quickly put the two in touch with each other, and gave each two credits, one to refund for the mix-up, and another to cover the postage of mailing to the correct recipient.  Everyone seemed happy with that, and the two people couldn't have been nicer!

In general, I think people understand that mix-ups could happen, but it's how they're dealt with that makes or breaks a transaction.
