Logos. The price of this book is ridiculously expensive. It's a book that's available in the public domain for free. Indeed you can find it for free at Monergism. You can get it for 99 cents as a Kindle book and about $11 as a hardback from Amazon or WTSbooks. Why in the world are you selling it for $20. The only reason someone might possibly consider buying the digital version of this through Logos (as opposed to the 99 cent Kindle edition) is because of the way Logos editions make Scripture citations easily accessible. But guess what? This book is a historical/structural analysis of the different traditions within Christendom and hardly has any Scripture references. So 99 cents for Kindle or $20 for Logos. I know which one I will purchase. Logos, please lower your price for this item.
