I think you should re-check the price.

I remember when e-books were first being introduced and a more intelligent world laughed in their face when they tried to put a price on them. It's something that should have just been included with your purchase of the real book to sweeten the deal a bit and show appreciation for your patronage. They were lucky to get a quarter or 50c for several years. More importantly to note is the fact that the publishers ultimately accepted that quarter or 50c. It was worth it to them to still offer it at those prices. They've slowly been conditioning everyone to accept higher and higher prices while giving them less and less. Now you have Faithlife and Logos, literally peddling the word for countless thousands of dollars. Consider that the Ancient Christian Commentary on Scripture is grossly overpriced at eStudySource for $149. That's $149 for what amounts to a big text file. But here that text file is $499! Wake up people.
