I dread work this week; odds are far too high that at least one bozo will come in every night, all excited about this, and wanting to talk about comics and collectibles as "investments".
He won't want to buy things, per se. He'll want my advice. What should he look for? What should he buy? What's the best return on his money?
How can he make a quick buck?
Your Obedient Serpent is honestly sick to death of comic books, superheroes, and pop-culture ephemera, but he'd still rather deal with people who read and enjoy these things than someone who bumbles in asking questions so clueless they defy an answer, simply because he's heard about someone who made huge returns on stuff that he's always dismissed.
How can you make a quick buck in the comics market? You can't. It took seventy godsforsaken years of carefully babying a fragile bundle of crappy, high-acid paper, starring a character nobody in the industry thought would catch on, to get that ten-million-fold return on Action's 10¢ cover price, you idiot.
Resolved: I am going to do my damnedest to sell these sleazy fools every worthless piece of crap I've got in the store, every random Big Event Comic, and most especially, every High-End, Hard-Sided, Nitrogen-Filled Comic Preservation Device I can dig up.
Because that's the real answer to the question. How do you make a quick buck in comics? By selling crap to the gullible.
Barnum was right.
