There is no doubt that the series Sex Criminals from Matt Fraction and Chip Zdarsky is a hit. The first issue went through a first print, two basic reprints, and then a goofy, fun, Olan Mills style 4th print.
Well, that goofy, fun Sex Criminals #1 4th printing is going for multiples of cover price. The highest closed price thus far is $15. There are copies currently going on eBay that are up to $17.00. All the listings for cover price copies are long gone now. A spot check of some of the on-line retailers shows they have been snatched up. There are only six copies currently on eBay.
