Just rethinking of some things I'd done in the past to save $$

Needing to save some major $$$$ here now, so rethinking of the things I used to do.

Hamburger - boil it, instead of fry. . .easier, less messy, less hands on time for me.
Drain and save the water - cool in the fridge, and use the fat for later cooking, the water for soups, etc.

Navy showers - get in, get wet - turn the water off. . . soap up, including your hair. . . then turn water on and rinse. Saves water, and sewer bills if yours includes water usage for the sewer fees.

Baking my own bread - kinda gotten away from this, but it saves money, and is healthier too. I think I'll get a sour dough started tomorrow.

Any other retro ideas, you do?
