I've gone to amazon before - they often have good prices on used books - and I have downloaded a bunch of this guy's books free, in PDF format - this is the only site I know of where all the materials are available for free download, even those he has written that are in stores, eventually - I have a bunch of them, but have been in the bible enough so that I haven't made time to read all the books I have.
Here's the site:
Christian Resource Library :: Desiring God
I have found this site's books to be fairly reasonably priced, recently finished "The Truth War: Fighting for Certainty in an Age of Deception," and just got "The Gospel According to Jesus," which I have wanted to read for years - and have yet to start
GTY Resources
Really, it depends what types of books I am looking for, doctrinal, expository on a book of the bible, apologetics, etc.
By the way, where is Books a Million?
Love in Christ,
