There's an anime store in Falls Church, VA that 
I've been too.  They have about 5 or 6 books of 
cels.  It's somewhat hard to find though because, 
it's in a shopping center.  They used to have a 
store in Fredricksburg but, it's closed.  Here's 
there website address it has there store address 
on it.
