Would you consider it unpostable if the flimsy box that audio CDs come in is all taped up?  There's nothing wrong with the CDs, its just that the box is all covered with tape, to hold the box together, and it's not pretty.  Thoughts, please. Terry

From the Help Center:

• Audio books must be originals.  They do not have to have their original box, but they must be packaged safely in transit and they must be playable.  Audio books are worth 2 credits.
• Audio books = books that were also published in bound form, that are read aloud by a narrator.  Audio recordings that accompany a bound book as supplementary materials do not qualify as audiobooks.  Performance recordings (ie, comedy routines) do not qualify as audiobooks (performance recordings on CD can usually be Posted at SwapaCD.com)

So yes, I would say the audio book is postable. I would consider the box kind of like the dust jacket--doesn't really need to be there and it only matters if the person has a RC regarding the condition.

Since they don't even require the box to be postable then no it's not an RWAP.
