Hi Michelle!

Those books should be fine to post.  Not all wavy pages in books are due to water/moisture damage.  Sometimes they are caused simply because the paper used to make the pages isn't the highest quality.

I've noticed this becoming more and more common.  When I've had one of these, I've sent a PM before printing the address.  Just to let them know.  So far everyone has accepted. 

If it's a WL book it's a little trickier.  For a WL book I would post it in the book bazaar and find someone to post it directly to their WL.  Just explain that it's not water damage but that new cheap paper.

Michelle, I had a book get wavy in transit to someone!  At least yours is already like that so that you can make the recipient aware of it.  From my prior posts on this topic, it seems like most people are fine with this...I unfortunately happened to send to someone who wasn't.  Oh well.

When I read a book the pages get a little wavy....something with the way I hold it.  Anyway, so after I read it, I stack a few books and put the one with the somewhat wavy pages on bottom.  A day or two and it's usually fixed.
