Hi, I did end up buying it too! I love it so far and i had a question for Jason and he emailed me right away! have you tried doing it by oz? So when you sell a tart you are selling an oz not a lb for a dollar. That is what i did with my products. When i entered in my wax i said that i buy by the case but the units i used where oz. So it is 960 oz per case(16 oz x 60 lbs). So when i made up the componets in my wickless i put that i used 15 oz of wax, 1.8 oz of fo, and one glass jar and it calculates the cost of each. i hope that makes sense. (i haven't figued out how i am going to do color cuz how do know how many drops in a little bottle?)
