How exactly do you order Kodak RA-4 chemicals and paper?

I looked around at their website, but I can't find where to actually buy it.

It is Kodak Alaris, not Eastman Kodak, and they only sell wholesale.
You need to deal through a retailer like Freestyle (?) or Unique Photo.
The paper is only available in rolls, unless you find someone who is buying rolls and converting them to sheets.

Unique sells smaller quantities of Kodak Alaris Ektacolor Developer Replenisher and Bleach Fixer, they carry most all Kodak Alaris chemistry. Shipping is UPS ground in the US. Like Matt mentioned KA paper is only sold in rolls.
