Comics were a lot cheaper in the 80 and 90s too. Most went for $1.99 or $2.99, kids could convince their parents to get them one at the store and people were more likely to grab it for that cheap.
Now they are $5-7 a pop, and in today's economy where most people aren't making wages much more than what they were in the 90s, many people have to turn away from those purchases.
