I’m not sure this is as much of a novelty as people think: The Borders near me always had a large selection of comics on its newsstand—mostly Marvel, DC, and Archie—and while they were set off in a corner, they were very visible and the selection was good. Since my store is gone, along with hundreds of other Borders stores, B&N may simply be picking up on an unfilled niche.
Todd makes an interesting observation:
The Marvel titles were all marked “Newsstand” and priced $3.99, with the exception of Incredible Hulks. That one went for a massive $4.99. That means some $2.99 titles jacked up $1 for newsstand and some $3.99 titles staying steady. I have no immediate explanation for the Incredible Hulks price.
