I have found the best way to save on auto expenses in our area is through Advance Auto. They always have coupon codes to score big discounts! For example, you can get 15% off right now using code: MR3T. I scored our brake rotors a few months back with 30% off, free shipping, AND 10% cash back through our bank rewards! (I am blessed to have a hubby who can change these.) Some parts can't be shipped like batteries, BUT you can order for in-store pickup and still get your percent off!! Go HERE to sign up for their email alerts, and you will always know what discounts are current!
