even the Goodwill folks weren't interested
In my experience (assuming you're talking about actual Goodwill and not just any-old thrift store) Goodwill is incredibly picky about everything. I don't even bother with them any more; it's pointless. If it's up to their standards, I have no desire to get rid of it.
I'm assuming the same, as it was the store mentioned by name. We have a Goodwill
outlet store near us, where you can
buy stuff by the pound (though not books), so they obviously take in more stuff than they can get rid of. Having trawled through some of the bins there, the Goodwill folks in our area aren't being as picky as they
could be.
