Are comics really meant to be disposable? I never got that feeling. Newspapers are disposable because they become obsolete within a few hours so they get tossed. Fictional stories last longer so story books, magazines, and other such media get held on to.
When I was a kid, I wasn't going to throw a comic book after I spent $10 - $15 on it. Especially when they were rare and I might not see another one. That would've been nuts.
