Good Day Cavers,
I apologize for this inconvenience, however the price listed in the November NSS News for the book Cave Biology Life in Darkness is incorrect. The regular retail price on this publication is $60 for the paperback version, not $43 as the magazine suggests.
If you have any further questions regarding this publication please feel free to contact me at (256) 852-1300 or Kelli@caves.org.
