I buy my film (Kodak and Agfa before it was discontinued) from my local professional photofinishing lab...

Labs have to buy papers and chemistry for themselves... They often also stock film etc. for their customers. Just because you don't see it, doesn't indicate that it isn't available.

I place my orders now for product using a simple email and swing by to pick it up when it arrives or when I'm in anyhow... I'm sure there is a lab that would be more than happy to be a supplier for you. Call around!
