Full set AMCS newsletters

[jef]

I have a full set of Association for Mexican Cave Studies Activities newsletters. This is a complete set from 1965 to 2013 (last issue is #36, June 2013). The 4 volumes covering 1965 to 1974 are hardbound. After that, they are numbered from 1 to 36, and numbers 1-10 are hardbound, others softbound. Each issue is about a hundred pages, and reports on all significant explorations and research in Mexican caves.
A full set of softbound issues would cost about $327 if purchased new (and some of these are no longer available). I am asking $150 for the set, plus $30 for postage. I'm not willing to sell them except as a set.
