gazzmania150 Batman has immensely more issues than One Piece. Because one piece is so old, a majority of people buying the actual volumes are primarily collectors, but the people buying volumes of newer manga range from deep rooted manga collectors to people who have mever seen a manga in their life. All the people I know that are reading one piece are reading it online by chapter rather than buying volumes.

Is this including the amount of people that just read the individual chapters through a shonen jump subscription? I want to buy all the volumes at once, but I haven't saved up enough money nor do I have a place to put them yet.
