DC's prices have gone up to 4 dollars
They might lead to sales going up short-term, but long-term, it's bound to discourage more loss of readership for pamphlets.
And, if I noticed correctly, even some independent publishers have been raising their prices that much for monthly pamphlets, which really isn't wise if they ever wish to make it big even with people new to the medium. But I guess they don't. That's why there's such an insufficient effort to advertise comics outside their own press.
