Sad but true... only one issue of Y: The Last Man remains. Still, that just makes now a better time than any to pick up the series -- you'll be able to plow straight through from beginning to end without any of the painful two month waits after each issue's killer cliff-hanger ending!
Obligatory t-shirt 3-pack reminder! If you order 3 shirts before November 30th, you will save $7! ($12 for international orders!) You will also make the cover of TIME and ascend to a higher plane of existence. Possibly. Why risk it?
