I've been thinking about little habits I have that save me money even though that was not the intention, it just turns out to be the benefit.

For example, my car has a delay on the lights. I can set it anywhere from 30 seconds to 3 minutes, and that is how long they will stay on after the car is turned off before they switch themselves off.

For years now I have had it set on the 3 minute delay because that is approximately how long it takes me to get everyone and all their stuff out of the car and up to the front porch and get the door unlocked and get inside. So I don't have to leave the porch light burning all day long if we leave in the morning, knowing we won't be back until after dark.

Now in the beginning this was just a bad habit of mine to forget to turn on the porch light, but now I consider it a good habit that saves a bit on the electric bill.

Anyone else have this sort of habit that unintentionally saved them some money?
