You can really save a lot of money by buying larger bottles like 2 liters instead of the 20oz bottles. You get a lot more, and a lot of times the larger bottles are cheaper too. I can pretty regularly find them for $1.00 on sale and the little bottles range anywhere from $1.49 to 1.69 at the mini mart. But then again, it is best to try to cut them out all together. I am not there yet, but at least I am saving money when I do buy them.
