B&H has put a new set of academic books on sale. These are $2.99 instead of the $.99 that I got spoiled on, but I'll probably spring for one, anyway. So far, prices are updated at Christianbook, Barnes & Noble and Amazon. Christianbook has DRM-free epubs, so I'm linking there.
In Defense of the Bible edited by Steven B. Cowan and Terry L. Wilder
Christianbook Amazon
The Problem of Evil: The Challenge to Essential Christian Beliefs by Jeremy A. Evans

James: Exegetical Guide to the Greek New Testament Series by Chris Vlachos

There are a few others that were either on sale before or don't suit my fancy, so here's
a list of B&H books sorted by price at Barnes & Noble if you want to browse.
