The oddest things seem to happen to me here on PBS. 

Today, I received a book I ordered - it is book 5 in a series of 15 or so.  But the sender sent not just book 5 (the only book I ordered from her) but also in the same package was book 6. 

So I check my bookshelves in the living room - I already own book 6.  I check my account - no requests from me for book 6 for this member.  I check my transaction archive to make sure - yep requested and recieved book 6 some time ago from the a different member from whom I requested book 3  ( I must have seen book 6 on her bookshelf in the 'buy more from this member' look see I did when I ordered book 3 - still, different member and a past completed transaction).  Hmmmm.  New member mistake, I think - no, the member has been here since 2007.

So now I have to figure out how to word this PM.  - Was the member intentionally generous, or mistaken? 

Well, it is a much nicer hitch than a RWAP certainly - but I'm begining to think I'm a complication magnet.

(In other odd but good news - I mailed 3 books to 3 different locations on Tuesday - late in the day.  All heavier items - all went media mail.  To my surprise all 3 book were marked recieved TODAY!  (USPS can sometime totally amaze me))

She didn't ask for a credit for it so why don't you just say thank you and post it?   I think someone was doing a ROAK for you.

I agree, it sounds like someone was just trying to be nice, although it does seem a little presumptuous to send the extra book without mentioning it. She might've saved herself a wee bit of postage if she'd simply asked if you'd like to have it first. I would just post the extra book to my PBS shelf and then (in case she happens to notice it there) say something like:

"Recieved __________ (the book you ordered) today, and there was another book by the same author, ________ (extra) in the package. I just want to make sure you didn't send this in error--if you were just being nice, I do appreciate the gesture, although I must admit that I already have this book so I will be posting it to my PBS shelf.

Or something like that.

Thanks Cheryl, I like the way you phrased that and will write something very similar.  I have trouble phrasing things in writing - without the human interaction I think I come accross as accusatory even when that is the last thing I am.  So, you've helped me out alot!

I often throw in an extra book as a surprise (the next  book in a series,  the same genre or author, etc.), but I always include a sticky note so they know it's a freebie book.  

Is it postable? I would definately PM her. She may be looking all over her house for this book that she was supposed to send to someone else.  Not realizing that she stuck it in your package. If she's a boxer or had a deal going or something she might be freaking out right now.  Then if it was a RAOK then thank her and post one of your duplicates. YOu can't have 2 of the same ISBN on your shelf at the same time.
