Not hard to guess which book carried Wednesday. Superman Lois and Clark #8 takes the honor this week.
The book sold out early on all the big online shops. It was selling for up to $14 last night and is selling well at $10+ this week. Larry of http://www.larryscomics.net mentioned that the book was originally solicited with a different, less desirable cover, and switched to the “Norman Rockwell-like” cover when shipped. Stores may not have ordered heavily on it as a result.
With Rebirth happening now, and the introduction of Superboy to the New DC Universe, the book where he gains his powers an dons a cape could be key.
There are currently 79 listings for the book, so if you missed out, you can grab copies of Superman Lois and Clark #8 on eBay.
