Hm. I'm not sure. I mean, I didn't discover comics by seeing them on racks -- I discovered them from other kids in schools.
I guess that makes sense. I wasn't in school, yet, so that wasn't an option. I grew up glued to the TV, and could easily have planned my day around when Batman reruns or cartoons were on, if anybody had let me. If I remember correctly, my mother picked up a Batman book on a cigarette run.
(Best guess, sifting through the GCD, was that this would be late 1980, if anybody's curious. I actually would've been in school, first grade. Which is odd, because I was reading paperback novels by then, and I'm not particularly visual, so what sense would comics have made? Oh, well. I'm not disappointed, just a bit confused how that all worked out.)
And they didn't close down!
Zowie.
But think of it this way! That's a much more entertaining story than just saying, "I went to the local convenience store and bought some comics from the spinner." 
True, but such a pain in the neck. I'm surprised my parents didn't throw me out of the car! I'm also surprised I never got there to see the place wrapped in police tape...
The other good shop story (which I think I've mentioned), when I was probably fifteen, I went into a magazine shop, and it turned out that they had crates of older comics in the back dirt-cheap under a table. I bought a few and came back a few weeks later. The comics were gone, and when I asked, the clerk claimed that they never sold comics or even magazines, and had always sold adult videos.
(I occasionally wonder both why nobody had a problem with a minor shopping in their store and why I didn't notice what they were selling.)
Today (no, I haven't gone in; I pass it on the way to work), it's actually still there, now named "Adult Video," which is probably a bit clearer.
More seriously: I take your point. Comics shops have also been notoriously unfriendly to women who buy comics.
If it were just women, I could almost accept it (not in an "it's acceptable" way, but in a "most men don't wonder what it's like to shop in a skirt" kind of way). But a lot of shops seem to go out of their way to alienate everybody they can. But I can go on forever about that, and I need to get cranking on dinner soon.
I will say that I also had the pleasure of shopping regularly at one of the best comic shops I've ever seen. They were in a mall, off the food court, oddly. The place was well-lit, all the new comics were within arm's reach of any adult (no bending, no stretching) on custom easels, plenty of room to walk around, and a very friendly staff with well-rounded backgrounds. Little kids would come in to talk to the guy who was getting his degree in archeology! Older kids would come in to drool over the pretty manager, too.
No back issues, but other than that, very, very well done, and they did a ton of business.
That fell victim to corporate shenanigans. Somehow, the owner sold the place to a video store (a few doors down) that wanted to target a younger demographic. Somehow, that meant adding video games to the mix, which slowly expanded and ate up the space, eventually dropping the comics. That took about two months, and the place closed about two months after that.
And the manager married her boyfriend. Grrr...
Hm? Where was I...?
Jim Shooter's blog had some interesting comments about the impact that mob schemes had on distribution. He argues that the original distribution model would have put them out of business. He also now argues against the current model.
It probably made more sense for Marvel. I think their distribution was always shakier (including the years they were distributed by a DC-owned company), so a tiny problem could easily have killed them, yeah. With the power of Warner Brothers behind them by then, though, I can't imagine DC needing to circle the wagons.
That's something that baffles me today. With DC owned by (AOL?-)Time-Warner and Marvel by Disney, why do they even acknowledge the presence of Diamond or Comixology? They could
accidentally distribute better than they are now, relying on flaky and adversarial third parties. It probably wouldn't cost them more than pocket change to make sure half the kids on the planet were buying their books every month, and letting the smaller companies ride on their coattails (and taking a small cut of their business).
I think that 99 cents marks a good price point for digital comics. No overhead other than paying the creators or giving them royalties. Next would be advertising or product placement. Then the most important would be a good plan to promote digital comics. Digital comics could be the salvation of the industry if done right. I wonder how much creators are making via Wowio, DrivThru,graphicly, etc.
The real problem with digital is that you need to get it in front of people, literally right in their face, to make the sale. I think there's potential, but it's hard to get around the enormous obstacle that they need to know to look for you. It's like moving to direct distribution, except the comic stores are all invisible and not listed in the phone book (you guys all remember phone books, right...?).
The best thing about digital is that you can do some pretty fancy market segmentation. You can sell at a higher price on the release date, for example, and drive the price down as the content grows stale. This way, the addicts (and pirates, if that's a worry) pay a premium, and the people who heard about the title and want to try it out can get a couple of issues for peanuts, and you can get that lower price forever.
If it was entirely up to me, I'd say that a scale from $2.50 down to about fifty cents would be a pretty good deal, lower on the low end, if you're very worried about piracy (because you're competing with free), lower still if you don't do downloads or insist on copy-protection. A really fancy system would let the user spend another couple of bucks to get a printed-on-demand copy shipped in, maybe signed by someone relevant.
(Sorry, I'm a programmer. Half my professional life is kicking around ways to distribute digital stuff.)
