@ArchivistsAlley @JustinHowe Yeah, I mean, at least on Amazon (and sites like Abebooks) I think at least some of it is people setting up automated pricing with screwed up settings or rules, etc.:

(But occasionally the seller really is setting a crazy price for something.) @ArchivistsAlley @JustinHowe I did once email a seller and ask, “Hey, is this price an accident? It seems unrealistic,” and the seller replied that he does indeed sell one copy a year of that book at the crazy, inflated price, and storing it cost him nothing, so it was worth it to him to do so. *shrug*
