Please change it back

This app use to be the only reason I got an IPod and the only reason I bought iTunes credits was to buy comics on this app. But now its almost useless since I cant buy using in app purchase and Im too young to own a credit card I cant buy on the website leaving the app useless. Please give this app in app purchase again.
