Food, and sometimes I make lamps out of things I find. I was making vinegar, but it attracted too many fruit flies. I make my own workout supplements too, from pre-workout drinks/caps and protein shakes (which are only whey isolate, dextrose, and quick oats; buying dextrose that the LHBS is how I got into cider making by the way!), to capping up amino acids and other supplements.
Buying the ingredients in bulk has saved me thousands of dollars over the years, plus I sell some of the things I make to friends, so they get to save money as well. Its a trip how much this stuff costs at the store, online or in real life, and all of the ingredients that are just fillers or so under-dosed that they are useless. Bulk caffeine caps come out to about 10 cents for 200mg, which is basically a strong cup of coffee, or a can of Rockstar or Redbull. 10 cents or $3+? Don't make me think too hard! Bulksupplements.com is the bomb. I also bought 144 pounds of whey protein for $189. A "high quality" 4 pound jug of protein powder can cost up to $80, again, a pretty easy decision. When I was bodybuilding, I was running through protein powder like nobodies business, so again I saved heaps just buying in bulk and making my own mix tailored perfectly to my macro-nutrient requirements for a given meal (was eating 6 times a day and every meal was measured out for protein, carbs, and fat, and timed for when my body needed whatever amount of macros)
I also make a blend of potassium and magnesium for my daughters menstrual cramps. It kind of works sometimes. Jams when fruit is ready, usually plum and/or blackberry.
