Miscellaneous volumes of "The Preacher's Commentary" set, edited by Stuart D. Briscoe, are marked down at Amazon. It appears to me, from several pieces of evidence, that the whole series may going out of print.
The entire 35 Kindle-volume set is now only
$99.99--which averages less than $3 per volume! Many, if not most, of the individual volumes are marked down.
I may buy other volumes, but I've gone ahead and purchased Volume 23: Micah / Nahum / Habakkuk / Zephaniah / Haggai / Zechariah / Malachi. It is
$4.99 (the price of $19.99 is marked through). I didn't take time to vet this 500-page behemoth for myself, but purchased it on the basis of great ratings and reviews, though few in number, that the book has and the reputation that the writer, Walter C. Kaiser, Jr., has as an exegete.
