Price of back issues?

This may be nice for users current on the series, but the cost is too high for collections. Also the cost of volumes is more then the price of buying each issue separately from within the same app? Pricing is just not in the right ball park when I can buy a physical bound copy of the first 50 issues at $58 MSRP, while the same from this app is between $100 and $150. I would feel taken advantage of to use this app.
