Amazon has the Kindle edition of
Thru the Bible 1-5, by J. Vernon McGee, a five volume set, currently marked down to $6.99. The list price is $90 and the Hardcover is selling for nearly $120. This isn't a small book, either, weighing in at over 12 MB in size. The description has obviously been copied from the Hardcover edition and there is some confusion as to whether there are five or 60 volumes in total, but this appears to be the "complete" set of commentaries (although it doesn't appear to contain the index to the set, which is sold separately in Hardcover)..
Book Description
A complete reference edition of the 60-volume Thru the Bible commentary series, this five-volume set is an excellent choice if you need a complete Bible commentary in durable hardcover bindings. It includes Dr. McGee's insightful study of each book of the Bible with in-depth, paragraph-by-paragraph discussions of key verses and passages. Purchase the entire five-volume set or collect them individually as your study progresses.
