Ah, the 90s. . .
I distinctly remember catching some TV hucksters hyping-up and guaranteeing the astronomical value increases in the newly release SUPERMAN HUNER/PREY and the introduction of the new Batman, Jean Paul Valley.
As a dumb kid, I actually got hyped-up by these sales pitches and the salesmen (who I'm sure never read a comic) made them sound freakin' awesome!
Definitely never saw comics for sale on QVC, but I never watched much QVC. I used to enjoy watching infomercials. They were always so ridiculous that they were funny
