you can buy the stuff in powder form. As such they're
usually supplied in "hobbyist" quantities from ads in
Nuts and Volts and similar periodicals. I don't have
specific vendors, sorry. Maybe the Thomas Registry
could help for larger quantities, but it seems tomes
like that are going the way of all flesh. They're
probably online though.
Of course Radio Shack sells the itty bitty bottles.

Does anyone know of a good supplier (in the US)
of
ferric chloride for
etching? I'm looking for one or five gallon
containers.
When I was doing more of my own PCB work, I'd just
buy the stuff from
my local chemical supply place. I'd buy the
technical grade, which
came in large chunks (just add water) that came by
the drumfull. I
seem to remember that it's also used in sewage
treatment--so if you
have contacts there, you might be able to score
some.
Cheers,
