(Trying to describe as best I can, as I don't have photo sharing capabilities around here)

I received a brand new hardcover WL book (bought from Amazon.com, delivered to my house). When you look at it from the top & bottom, every  single page is wavy. It doesn't look like someone dropped it in the bathtub, and I'm inclined to chalk it up to a tight binding, as the paper is pretty heavy paper (not the cheap MMPB paper that waves easily). Looking at the book from the side, there is no evidence of said waveage.

Opinions?

Wavy pages don't really tell much these days. When you open the book, do the pages look like they have sustained liquid damage? Is there an appearance of a stain or texture change? Do they feel stiff or "sound" really rough? You being the only one with the book, you are the only one who can really tell if it is normal paper waviness or liquid damage. "Waviness" is not against any posting guidelines. Liquid damage is.

I see plenty of brand new books with that waviness. It seems especially prevalent in YA and kids books, which seem to be bound more cheaply than "adult" books.

So, I agree, without any other evidence of water damage (staining or texture changes), I would consider the book postable.

Timely question Jennifer, thank you for asking. 

I just sat down at the computer to accept a request for a book I posted a few days ago.  As usual, I do one final inspection before accepting a request and see a couple pages are wavy on the edges.  No thickness, puckering, or discoloration.  The pages are not even together but spread throughout the book.  I'm fairly certain I purchased this book new, it didn't pass the 10 page rule so I set it aside hoping to try again later, and it's sat in a dry box for about a year with other undamaged books. 

It's in exellent (even pristine) condition except for wavy edges on 2 or 3 pages...to post or not to post?

Thanks for the opinions, ladies! I know it's hard without pictures. As far as I can tell, there's no texture change to the pages, and definitely no staining/liquid lines. There's no way water damage would affect pages one way and not the other if Every. Single. Page. is wavy, KWIM? I went ahead and posted it, since I was #1 on the WL and bought it because I didn't think I could wait.... I don't think it's water/liquid damage, but cheap binding, as Sara suggested.

I've noticed that a LOT of books seem to have waviness nowadays. I think that more and more are just coming that way.
