Buying as you go is how I will do it too. Dh likes having the Replenish package for lattes, OJ, water...but I just can't get it to work for me. I end up having two lattes a day when I just drink that much dairy. I don't drink OJ, even fresh squeezed, more than once in a blue moon. Etc. So I get an Evian package because I do drink spring water, and then buy A latte per day, and I'm good. Maybe a beer every other day. The packages just don't work for me.
