So that would be a no go on splitting it up and saving it? I'm a student and would like to stretch the money, if not, nbd.
Most chemistry can be saved - just not frozen!
You need to get more input though from those who are using that particular package about the specifics of how to do so, so you may need to wait a bit until a few others have a chance to respond to the thread.
“Photography is a complex and fluid medium, and its many factors are not applied in simple sequence. Rather, the process may be likened to the art of the juggler in keeping many balls in the air at one time!”

Just mix everything up (using water that is heated up and cooled quickly to drive out air), store in PET BOTTLES with ALL AIR SQUEEZED OUT, possibly refrigerated but NOT FREEZED (don't go too near the freezing point). It will keep for at least 6 months. Storing the concentrates is very difficult and usually leads to shorter shelf-life than with mixed solutions. Also, measuring everything out every time is a PITA and error-prone.
