Sneaky frugalities

This Frugal Friday, I want to talk about what I call sneaky frugalitites. There are plenty of big, obvious things I do to be more frugal in my life, but I never want to forget the sneaky little things that I do. These are the things that stretch everything just a little farther, or make it last just a little longer, without anyone even noticing or feeling the difference. For example:

I empty free sample packets into my shampoo and body wash bottles. I used to try to use the packets, but it was a terrible pain, and plus this helps me decide how much to use, instead of being bound by the "single use" packet.

I sometimes add a cup of reconstituted milk or frozen concentrate orange juice to a half bottle of their fresh counterparts. It's not enough that I notice any difference in taste at all, but it stretches me to my next grocery day and saves me a run to the store.

I add a little bit of water to liquid hand soap and dish soap. Again, not enough that there's a noticeable change in consistency, but enough that it makes it last longer. I know I could just use less, but I don't need to ask everyone who washes their hands to use less.

I whip my butter in my stand mixer. This one is a bit more trouble than the rest, but it actually gives the butter a nicer texture, making it easier to spread, while at the same time mixing in air to increase the volume. This way less butter seems like more, saving us calories and money.

If I serve a stirfry, or other dish containing both meat and vegetables, two nights, the second night I'll just add more vegetables to stretch it a little further.

What sneaky frugalities do you have?
