Cost more cost more who really cares. If I bought manga I would spen d another dollar or two on a coloured one, where you can understand all the fights and movements without a problem really.
Cost more etc etc, really guys, Naruto is the most popular manga now, it's monopolistic it doesnt matter how much does it cost, 10$ or 20$, the consumption wont change because people who buy it and not download wont notice the difference.
But you see some people inclu7ding mysself have pro9blems at understanding what are some manga scenes about, so it's better to colour the manga.
You guys are talkign about marketing without any knowledge of it, think a little bit about consumers or.. like us?
