Great app but… $$$

Everything about the app works perfectly for me, the biggest concern I have is with the prices of the comic books themselves. Reading them is extremely enjoyable with the interface presented, but its hard to justify the price tags.
For example: the "Civil War" story ark is being sold for $20.99 CAD on the Marvel app whereas a digital copy of the same book on the Amazon app is sold for only $6.20 CAD.
This is the best digital comic book reading experience Ive had on my iPad, but the inflated prices cant even compete with the competitions. I want to love this app, but its too rich for my blood.
