Gordon Fee has 3 NICNT books on sale but the Revised Edition of The New International Commentary on the New Testament: The First Epistle to the Corinthians is not. The older 1987 version is on sale. I would buy the newer one if it was on sale but probably not the older unless someone convinces me it is better. Anyone want to convince me I should buy the old one? Which one comes in the full sets or do they both?
