Even better, there is a $2 coupon for M1 jugs in the little brochures at the sample tables and the 10% off is taken after the $5 auto dept coupon but before the $2 coupon and comes off the discounted price of both oil and filter, so:
$45-$5-$.5(OF)-$4(oil)-$2-$17=$16.50 for a jug of M1 AP and an MI oil filter.
Obviously, you could do much better buying the package with a less expensive M1 flavor.
