C.S. Lewis's spiritual classic Mere Christianity is listed in Logos with a $12.99 price, but when you go to the product page, it says "This product is only available for purchase in one of the collections below", with the only option being the $400 ($380 for subscribers) C.S. Lewis Collection that basically covers all of his works except Narnia. Mere Christianity is at least available as an audiobook, but as for the text… to take a book so useful to seekers and apologists and hide it away in a package only Lewis scholars are likely to buy does the work a disservice. Why is it being marketed this way?
