Never under estimate what you might find in one of those discount stores. The Seven Sayings of Our Saviour on the Cross by A.W. Pink and An Introduction to Biblical Hermeneutics by Silva & Kaiser were both a grand total of $9.99 in a local discout house. (The bad thing is that it had numerous copies of the Emergent Church stuff by McLaren, Sider and others.) Looking forward to digging into Tactics by Koukl. I'll have a post on that next week.
