Try getting a hold of a mini lab supplier in your area first, then search one out
nationally.Their are a few photo labs out their that will ship chemicals allso,
Photoland in WI. did at one time.. Go to the the people that use them and ask them to direct you..
Hopefully you can find one in your area so you can pick them up, so you dont have shipping charges. For E6 ,recently a 10 L list was made on APUG ,copy it and send it to a supplier.
Personally i think APUG should try and get a photo lab supplier as a sponsor. It would help keep film alive, for what good is film if you cant get it processed.
Last, dont count on any major photo store except maybe Freestyle, they all have gone digital. Try a thread search for oher comments about chemical supplies..
Good luck, John
