Do you (or would you) post audiobooks that you have not listened to?  It's pretty easy to check the condition of a book that you have not read before posting it (from a garage sale or such), but how could you do that with an audiobook that you have not listened to?  Would you just visually inspect it to make sure the tape is rolled up properly, or spot-check (by listening to) sections on each tape, or just not post them?  I've been finding a lot of cheap and free audios (got a box from freecycle yesterday) and while I'll listen to many of them, some just aren't my cup of tea, so I'm considering posting them.  What do you do?

Definitely spot check them and look for scratches-- if any look questionable, I'd listen. (Or perhaps you have a friend who would be interested enough to screen them?)

Audiobooks seem to be very popular, so I'm sure there are members out there who would love them even if they're not your "cup of tea."

With tapes is hard to say.  A CD you can just look at to see if there are any scratches. It's also easy with a CD to pop it in and skip around to make sure it plays.  I guess I would just inspect the taps and make sure they don't look bunched up or knotted anywhere.  I would probably put them in to at least here the first few seconds to make sure they play.  Then be prepared to refund some credits if by chance one happens to be bad. Most likely that won't happen unless someone listens right away.
