The water meter's mechanism has some internal drag, so there may be a minimum flow below which you're getting water for free. I'm guessing this may be as low as 1 gallon per day or even less. I know that my water meter is very accurate at very low flow, so you may want to test yours.
IMO it's more important to save water than to save money.
