Bulk Art Supplies - Source?

Bingo thought this was worth mentioning said

I work with a sorta large regional music festival (~4,000 people) that takes place every spring (May, to be exact) in Florida.

We have a pretty big dedicated kids area staffed all day and night with activities, music, etc for the kids. One of the popular things to stock the area with is arts and crafts stuff.

I know Woot frequently sold those inexpensive art kits that came with a ton of colored pencils, markers, paints, etc.

Anyone have any leads on where I could buy bulk cheap art supplies? Doesn't have to be the sets like Amawoot sold though those are nice. Basically, just looking for a way to cheaply get a TON of stuff for 4 days worth of kids going at it.

Also, if Meh/Mediocre wanted to sponsor the kids area and stock it, we can work that out. A bunch of fenced in parents watching their kids - talk about a captive audience :)
