Using mouthwash? Only use a small amount and don’t fill up to the line the manufacturer wants you to fill up to. Washing hands with soap? Do you really need more than 1 pump, and a full pump at that? Using shampoo for your full head of hair? (Sorry Greg, couldn’t resist!) Use the smallest amount you can. How often do we take these things for granted and just go nuts and probably use too much. I find when something appears to be in abundance we use more of it, but all this stuff still costs money.
