About a month ago, I requested a heavily wishlisted book I thought was more about tips than recipes.  I received it, and it had staining on the cover.  Luckily, I flipped through it before marking it RWAP and, realizing it is 50% recipes, decided it's a cookbook and marked it normally.  I've read it, and the recipes are mostly too high in calories for me, so I posted it yesterday.  I PM'd the person it was offered to and explained that it is a cookbook and described the condition, and asked her to PM me back if she wants the book. 

As of this morning, she hasn't PM'd me, but did request the book.  I've PM'd her again using the "I think the computer's been eating PMs again" excuse and asked her to confirm via PM that she is okay with the condition of this book.  I marked that I will mail on Friday, which is honestly the soonest I can get to the PO.

As of right now, 10 members are wishing for the book.  

My question is, if I don't have a PM from her, should I cancel the transaction?  I don't want a RWAP.

From the Help Docs: (Highlighting is mine)

• • Cookbooks may have some mild staining, since these are used in the kitchen and while cooking, and some minor degree of staining could be expected in a used cookbook.  Also a small amount of writing in cookbooks could be expected
  • • HOWEVER, if you post a cookbook and it is stained and/or written-in, the condition must be described to the requestor in a Personal Message
  • • AND the described condition MUST BE AGREED TO in a reply PM before the book is sent
    • This is the one of the ONLY three cases in which a PM exchange about a book is required before the book can be sent (the others are for travel guidebooks and textbooks/workbooks--see above).
• this exception applies to the covers of cookbooks also.

So basically, if the person doesn't agree via PM, you must cancel the transaction.

Thanks, D. G., if she doesn't respond by Thursday, when I want to print the mailer, I'll cancel the transaction.

That would be the best choice Kirsten.  As posted above, the rules for coobooks and textbooks require that the condition of the book be clarified and agreed upon.

Unfortunately, you cannot access the other members on the wishlist afte/ifr you cancel the transaction.  The best option, if the 1st wisher does not want your book is for them to add an RC that you can decline (really doesn't matter what it says) then your book will be offered to the next wisher in line.

I would send 1 more PM on Wed stating that you will cancel the transaction by x time on Thursday if you haven't heard from her.  Ask her to set up a temporary RC so you can offer the book to the next wisher. 

Actually if you chose Friday as the mail by date, you have until Sunday to mark it mailed. So you could give her longer.  But I probably wouldn't.
