Ha! April Fools! actually they just flip fans the bird and tell you to buy more comics!
You got me.
DC generally runs an editorial explaining their price-hikes. I recall this back to 1974-1975. And the early days of Jeanette Kahn.
But I guess that's just a formality. And like heroin junkies, the leadership at DC figures readers will pay for their fix no matter what it costs.
