and i'd know, i've done enough of it.  
considering overhead--and just the high cost of 
EVERYTHING in nyc, it's prolly safe to assume 
there would be a considerable mark-up (i wouldn't 
know what it'd be like in l.a. where there is 
more anime-related shops).  while it's fun 
perusing in person, i'm gonna assume it's better 
getting things online.

i'm more than happy that there is a book-off ^_^  
mmm...cheap manga.
