17. Don’t forget to bring your own grocery bags
Some local laws require grocery stores to charge you for bags. The idea is to convince consumers to recycle. By reusing paper and plastic bags, you’re helping the environment. You’re also saving money by not paying a small fee for each bag you purchase at the checkout counter. You may only save a quarter or 50 cents per visit by bringing your own bags, but this can add up to $25 or more over the course of a year.
