at first I had that thought of "Yay I can just put my total spent amount in the first kit box ",

but then realized that maybe there was some calculating going on there w/that second carto box ???

IDK what's calculating what here .... I know the one I use now just multiply's cost of cigs X days past ...right ?

so my thinking is we need one that does that then subtracts $$ spent to get total saved ......

I have a spread sheet that does this, but I'm the only one that can see that
