I received a book with a torn cover (1 1/2 inches from the top, 3/4 of an inch from the bottom) with the first few pages beginning to come apart from the spine (near the top tear).  I marked this book as received with a problem and I asked the sender for my credit back.  She replied that she will give my credit back when I mail the book back to her.

I know this sounds silly, but i don't think i should have to pay to send the book back.  It was a young adult book and would not cost that much money, but should I have to pay to return this book?   What would be a proper response?

I appreciate all advice!  Thanks!

I checked the help section (there is a problem with a book I received) and this is what it says:

You are not obligated to return the problem item, but if the sender gives you an extra credit or postage to do so, of course you may.  Unofficial problems are noted during the process of marking a book received (on the survey portion of the Book Received page).

So if she wants you to return the book she should either give you a credit or the postage. I'd PM her and cut and paste the above from the help doc into my PM. She should be giving you your credit back regardless of her getting the book back.

ETA: sorry about the bolding--I don't know how to get it off!

To be more clear, she should return your credit regardless, since the book violates PBS conditions.  If she wants the book back as well, she should also give you money for return shipping (either by giving you extra credits or PayPal or whatever you want to work out). 

Sorry this happened to you -- I know it is frustrating.
