The new Mockingbird comic written by Chelsea Cain has been described as a puzzle box of a comic. Which is the kind of thing that doesn't always suit a direct market serialised comic book where if readers don't quite get one issue, they don't bother getting the next.
Bleeding Cool was the only site to report that Marvel would be sending out as many issues of #2 as a retailer ordered of #1, no matter how many they ordered of #2, and not charge any more money.
Well, now they are promising to match a retailer's order of #2 with #3 under similar terms.
This should make the series more profitable for retailers and encourage them to hand-sell each issue, in the knowledge that they'll make more money selling Mockingbird than other comics on sale.
