Some time last year, when I decided to eliminate certain yucky things from our diets (high fructose corn syrup; artificial colors, sweeteners, flavors, and preservatives), I realized that the alternatives were EXPENSIVE!  (until I found Trader Joe's, but even that didn't entirely solve the problem)  And when I wanted to buy cleaners that were non-toxic and/or biodegradable, well, how could I afford that?  Again, and again, I came up against the dilemma: how can I afford to buy the non-yucky versions of all these things in my life?  Sunscreen, shampoo, kitty litter, detergent ...

The answer for me was not to buy them anymore.  Instead, I've found that when switching away from bad-for-us products, there are two alternatives: buy a "green" or "natural" version of the product, or go all-natural down to the simplest possible way to do it.
