Man, you are really showing your ignorance!!!
Dr. Hovind is not a part of the Bible Believers Bookshop. And he makes very little money off the materials he produces because he does not copyright them. He allows people to copy them and do with them what they will.
He has some excellent materials at a great price. But he never tries to charge people more than what they are worth and if you called him today and told him you needed something and could not afford it, he would give it away to you for free.
I have personally seen him do that.
So stop trying to malign the guy and get your facts straight before you post lies about the man on a public forum.
Assuming what you say is true (Praise [insert your favorite deity's name here]!), you're talking about loss leader marketing materials. Done all of the time in business...and in religion as a business. Fleecing the flock. Most sheep are too dumb to recognize the shears. Say "Baa."
