I make my own saline solutions too. Well, I use water and baking soda for a nasal rinse.
Lots of "alternatives" cost more for me, I'm afraid. Acupuncture, for instance, isn't covered by insurance.
I do save money though buying cd's so I can do qigong exercises at home, instead of paying someone to teach me, for instance. I also don't take any type of medications or health problems because I live a healthy lifestyle so I think that saves me money in the long run.
