I've been in this club for four years now and never seen this prerequisite:

"I will only accept books that are tradable."

Aren't books posted to PBS required to be tradable?

None of my books have water damage or extensive wear and tear, none of them are missing a cover or ARCs, but neither are any of my books what I would call in "new" or "like new" condition; they are all clearly previously read books that are still in good shape.  Have the book requirements changed since I joined the club?  Or... does "tradable" mean something else that I'm not aware of?  I would assume that a book posted in the club would be tradable... that's kind of the point of pbSWAP, right?  Is there a problem with people posting books that don't meet the club requirements, or is this a further standard that I don't know about?

Rachel, I'm pretty sure that's just another way of saying they want books that meet PBS posting guidelines.  Unfortunately, there are instances of members receiving books that do not meet PBS standards and I imagine that this person must have been the recipient of at least one book that was unpostable.  

As long as my book met the posting criteria, I personally would feel comfortable posting to this requestor.  IMO, they aren't necessarily looking for like-new books just books that they can repost if they so desire.

I agree with Tamara.  I think it's just the requestor's way of saying she wants books she can repost on PBS.
