The Philatelic Book Of (Still More) Secrets, Vol. #3

Does anyone know where I can get a copy of the The Philatelic Book Of (still more) Secrets, Vol. #3? I've checked eBay and Amazon, and I've come up empty. Thanks in advance!

Check with the publishers at PSE (gradingmatters.com), but it does not look like they currently have any copies.

I haven't actually checked with them yet, but last I knew, they only had volume #2 available.

There is a specialist dealer in the UK who supplies out of print philatelic books etc. Worth looking at the web site

I checked Phil Bansner who usually has everything imaginable but does not have this.

I emailed the good folks at PSE (gradingmatters.com) and had an exchange with a lovely person named Marina. She informed me they have ALL three volumes of The Philatelic Book of Secrets! I ordered volumes #2 and #3 (my existing copy of #2 is falling apart) for the small sum of $15 each. This included postage. I'm not sure why this is not reflected on their website, but I'm glad they had more copies available. If anyone else wants a copy, I would highly recommend reaching out to them!
