Homemade Stuff WIN - last week, I made some deodorant according to the recipe linked below (I altered it only slightly; half as much baking soda, and all cornstarch, instead of half-and-half arrowroot powder). No shopping required - I already had all the ingredients at home. AND IT WORKS GREAT! I have rigorously tested its abilities: a day at the field site, baking in the sun. Even the next morning, STILL NOT STINKY. Seriously, this works better than any deodorant I've ever used - much better than the stuff from Lush, which works okay most of the time, but doesn't really hold up to extreme conditions. AND with none of the scary chemicals present in commercial deodorant/antiperspirants. Total win.
