Random Customer: I don't know why anyone reads Marvel comics. They're so expensive.
Me: They're the same price as almost all comics.
RC: No. DC comics are a dollar cheaper.
Me: No. DC relaunched them at a dollar cheaper, but they came out twice a month, so it was more expensive to collect them. And then they bumped the price up, so now they are the same price but ship twice as often, so it's twice as expensive to collect most of their books.
Me: Check the cover. Almost all of the titles that people read are now $3.99 just like Marvel.
RC: Then why does everyone say DC is cheaper?
Me: Because marketing is more powerful than truth.
Me: Back to your original question,a lot of people read Marvel because those are the stories they like. The same reason people should read DC comics or Image comics or Boom comics or anything else. Read what you enjoy, not what's cheapest. When DC comics were $2.99, they were a few pages shorter but with the same amount of ads.
RC: They were not.
RC: You're a Marvel guy, I guess?
Me: I'm a Read Comics I Like guy. Right now it's mainly Image and some Marvel stuff. But back around Blackest Night, I was buying mostly DC.
RC: So you have no loyalty?
Me: Nope. There are so many comics out, why would you waste time and money on a series you're not enjoying? I'd rather spend an extra dollar for something I'm enjoying or just not buy anything at all than spend money on dull story, in the name of saving a buck.
RC walks over to the shelves, gets a couple of All-Star Batman issues, and comes back to the counter.
RC: Are these any good?
Me: I haven't been reading it, but the people who liked Snyder's Batman run have been really enjoying it.
RC: Do you think it sucks?
Me: I haven't been reading it.
RC: Because it sucks?
Me: I have no idea. I haven't read it. It sells well. Nobody has told me that it sucks.
RC: That sounds like it sucks but you want me to buy it.
Me: I want you to buy whatever makes you happy.
RC glares at me, walks back to the shelves (leaving the comics on the counter, natch), picks up some more comics, puts them down, and leaves. Because nothing makes him happy.
