Are you interested in a review of their customer service, how well put together the books are or....?
As you know, they are a significant publisher of historic Baptist works. They are probably the only current publisher for some of these works. My knee jerk reaction is to say that their books are generally too expensive, especially when you can get many of them online for free. Most of their books that I've seen are paperbacks, but they look to be pretty sturdy. And in fairness, these aren't exactly bestsellers, so they probably have to charge a good bit more than Crossway or P&R would for new books since there is going to be limited demand.
I've never ordered anything from them, so I have no opinion of their customer service.
