I just stumbled across this forum as I was looking for COPHA substitutes, only to find that Crisco and other products are NOT the way to go. Been using cocoa butter myself, but wanted to try this COPHA out once. The website that was previously listed is a dead link. I did, however, find their new and improved online store that sells COPHA. They even have an app !! Woot Woot.

Hope this helps out at least one person, if not more. :-)
