This item is eligible for our 4-for-3 promotion. Eligible products include select Books. Buy any 4 eligible items and get the lowest-priced item free.I have just now noticed that these print version are now available on Amazon. Being an Amazon Prime member, the free shipping would now push me here as opposed to LuLu. I don't know how long this promotion has been in place or will last, but it seems like a good time to stock up on those Elder Tunnels you may have been putting off buying if that is the case for you.
