Each year I look forward to the annual holiday sale from Oxford University Press. They regularly have exceptional deals on prominent books. This year the sale is even better because they teamed up with Amazon. See the sale homepage here.
There are not many things in their bible/theology section that I like. They are good for broader reading, which brings back a point I have mentioned before: Pastors need to read broadly.
Some of the categories I particularly like from Oxford are: American history, world history and reference works. Happy reading.
