I've never bought Fuji chemistry from them, but Unique Photo seems to carry a lot of it. Unfortunately, their Web site is poorly designed, so it may be hard to locate what you need there. You might want to try calling them on the phone instead. Others have told me that their salespeople are knowledgeable and helpful, although I've never placed an order with them by phone myself.
Thanks for the link. Had a look around and was able to find most of their chemistry. Seems like they stock all the Fuji Hunt chems as well as Kodak's. Another good resource that may come in handy in the future.
