As I saw this morning on BibleWorks' Facebook page, WORDsearch is now offering the NICOT/NICNT commentary series for BibleWorks! The sale price for the whole set plus a few extra volumes is just under $1100, which is about 500$ less than it is available elsewhere electronically.
See the page at WORDsearch here.
I'm not really in a place to be able to afford such a set, but I am happy that it is available. I think for those who really desire to buy commentary sets in their entirety, this is a pretty great deal!
