if you normally bought 26 30ml bottles and you bought instead 60 ml yes youed only make 13 trips now if you were to get 90mls at one shot youed only have to make 7.5 trips per year I can not explain how you make a half trip and still end up with the juice but the numbers dont lie! ;-)
I actually made a .5 trip back in the late 80's. As soon as bail was posted, I made the other .5.
