Where to buy cheap Acme screws?

[DingbatCA]

Looking for a place to buy cheap, new, acme screws. I am based out of CA, US.
Looking for big screws, 1.25D (in) with a lead of .25, in 4ft lengths. Steel is just fine. Currently the best price I can find is $13 a foot.
Where else should I look?

HEHE, been looking on e-bay, with little to no luck.
I need big screws... Ebay has lots of little screws.
