Fuck me if I didn't forget something real important:
Recycle. Hey, Kalifornia pays at least $1.90 a pound for beer and soda cans which means I can cash in about $200 a year minimum. Check your own state and see if you can't score too.
And if you have any steel laying around in your garage that you're not going to use for projects in the near future, consider cashing that shit in at your local junkyard. Any kind of steel - angle iron, leftover plate steel, etc. I know that stuff is going for a pretty penny no matter where you live. Also check on the price of lead - if it's decent, go around to your local used tire shops and offer to take wheel weights off their hands for free. It'll save them a hazmat disposal fee and you'll have free lead for bullet casting (thanks for reminding me, MauserMedic) or you can cash it in for bucks.
Also, instead of taking your hounds to the vet for vaccinations, check your local feed & seed store. You can buy everything you need to give your own dogs their shots there, including syringes. My vet charged me $70 bucks for the series for years. When I got CharlieGodammit, Debbie told me about the feed & seed thing, and she did Charlie for $13.50, which included everything except rabies vaccinations. It's easy to do yourself. Hold your hounds' muzzle and tell him what an ass-kicking motherfucker he is, have a friend raise the skin on the back of the dogs' neck and slide the needle in under the skin. Pet him, give the dog a doggie treat and your buddy a beer and you're done with a savings of 50 bucks.
Rabies has to be done by a vet here in Kalifornia, but if you call your local animal control office they'll turn you onto a low-cost clinic. Same thing goes for a nut-cutting or spaying clinic if you're so inclined.
