>>108310640Comics (at least at Marvel) had three tiers pricing-wise by the end of the 80s:
.75 for most books (mostly Avengers books, Fantastic Four, etc)
$1 for popular A-List books and licensed books (Amazing Spider-Man, X-Men, X-Factor, New Mutants, Hulk, GI Joe, Transformers, Alf)
$1.50 for deluxe format books.
This had a bad effect as it made people think the .75 books weren't "good" since they were so cheap compared to the flagship Spidey book, X-Books and the cartoon books. And their sales plummeted.
It led to a blanket line increase to $1 at the start of 90s and then blanket increase, first to $1.25 in 1992, then $1.50 in 1994.
It wasn't until Bendis started shitting thing up, demanding the very best production-wise, that the two tier pricing ($3 and $4) was reintroduced, because it burnt Marvel badly the last time they tried it.
