Removing the ability to use anything other tahn credits in the app is really stupid, i hvae purchased over 120 titles the last year from the 1, 2 and 3 euro sale as well as the 2 for one credit deals. Having to visit the website just makes me delay the purhase until Im gping to read the book. I know for a fact that people like myself are willing to part with money for convinence and pay for stuff 'just to have it ready', your new way is not that and does not justify the money spent.
