This one is for the Department of anomalous pricing (like this one). Chris Anderson’s new book, Free, is about how things should be Free. The physical book isn’t free but some electronic ones are (e.g., here). As for the audiobook, the 6 hour unabridged version is free but the 3 hour abridged version is $7.95! That is not only not free but the whole pricing scheme seems to violate the usual economic assumption of free disposal. Talk about challenging basic assumptions.
