Just to let you know... I have made two orders to Calumet this month and both have had back-orders of color photochemistry. In the first order about a month ago, I purchased 2 Tetenal C-41 press kits and a Kodak 1 Liter E-6 kit, in addition to a few 5 packs of 100 + 400 Portra and Velvia 100. The order process got all the way to the confirmation page before informing me the Kodak E6 kit would be back-ordered for 3 weeks! Grrrrr....... OK, I can deal with that. Now, I run out the C41 Tetenal chemistry, go back to the site, note that it "ships the same day" according to the web page, order 3 kits and come to find that one kit is back-ordered for 2-3 weeks when confirmation is sent! Seems an awful shallow inventory for a National supplier to me... Do yourself a favor; call and investigate BEFORE you design a project around chemical availability as reported by a web page.
