Although I don't use hair color products, I know they're expensive, so why not save it until next time.

I have several ways of saving, one is that I use the bottle of vinegar to pour into glasses and my electric kettle - we have so much calcium in the water.

Another thing I'm saving on, is those little plastic bags on a roll, the ones they have in supermarkets for vegetables etc. I usually take a few extra and use them for Fister's litter. Oh, and bring my own plastic bags for groceries - if you buy one they cost 50 cents.
