If you are a pastor, student or general lover of Biblical and theology books, make the trip to the Trinity Evangelical Divinity School bookstore. Sadly, the Trinity bookstore is being transfered to an outside dealer. To liquidate their remaining trade stock the bookstore has everything, yes everything on 40%-50% sale. The Trinity bookstore carries a high level of pastoral, missions, apologetics, philosophy, Biblical language resources, theology, Biblical studies and OT and NT commentaries. Head over there if you are in the area. Yesterday, I bought my books for my summer classes and saved about $150.
