So last night I got this at this store called "2nd and Charles":
I've only ever read a few of the Bionicle books (not including the comics), so this should be an interesting experience. Each was around $1.70
Also got the Unwind series for $18, the first seven Negima! volumes (each costing around $4), The Ancient Magus' Bride for $6, 2007 Movie Classic Camaro Bumblebee for $13 and 2007 Movie Starscream for $30.
