Hi, where can I find these books:

101 Arguments Against Christianity
101 Cleared Up Contradictions in the Bible (the one edited and added to by Jayden Raine)
As Wise as Serpents as Peaceful as Doves
and About the Quran

They are supposed to be the best apologetics books / tools for defending Christianity and the Bible ever, at least according to him. I can't find them listed with b&n, hastings, borders, or any major bookstore, and not even Christian bookstores. Why?
