Just in case you're nearby one of their stores, you can now pick up a Mann Filter oil filter there instead of going by the stealership or ordering it online. The typical price is around $12.99 each (may vary depending on your area).
If you're getting one of them at advance auto just use coupon code P20 on Advance's website to get 20% off. There are better coupon codes if you buy more just look online for them.
