I was excited enough to see the first two volumes of the Hermeneia commentary on Matthew advertised as the free and $1.99 deals for November! It's always nice when a serious and recent critical commentary shows up (I'm still kicking myself for missing Brevard Childs' Exodus commentary).
But it gets even better! Ulrich's commentary is a three-volume series, and the third volume (on Matthew 21-28) is on sale for just $5! When I added it to my cart, the discount code showed up as "November Free Book of the Month Hidden Deal."
That's 1,844 pages of high-caliber academic commentary for seven measly american dollars. Logos, you have outdone yourselves.
