Same old song, get a new line already.
Making money is fine, but both parties should benefit. If you walk away from a deal knowing you fleeced someone, you shouldn't have done it. Capitalism says that's okay, but these are $5 funny books. Have a heart.
Just curious, does this thinking apply to dealers and LCS's, people who's business it is to know the product they sell for a living?
Your LCS has a NM Preacher 1 for $15 bucks, you gonna pass and tell him it's under priced? I don't tell my bartender they are not charging enough for a shot of Goose, it's their job to know that, it's my job to enjoy the great price on Vodka.
Nowhere in this are we talking about selling too cheap. What's happening is that people are over paying for a book like Supergirl 8, where the seller knows the buyer is underwater as soon as he walks away with it. I'm saying the asking price isn't fair, and the seller is treating that buyer like a mark, rather than a valued customer. Long term, everyone loses.
