Where have YOU seen Schlock books?

Photo by John TroutmanFriend, scholar, and fellow-cartoonist John Troutman snapped this lovely picture of a first-edition* copy of Schlock Mercenary: Under New Management in a bargain-bin at a used-book store. So yeah, somebody parted with their Schlock book for a paltry two or three dollars -- you know what? I'm pleased. Now there's a copy out there in the wild, looking for a new home.

But now I'm wondering if there are other copies on the prowl? Have you seen any? Let us know!

(*Note: Yes, yes... "only" edition. For now, anyway...)
