I did a similar thing last time. I used the online coupons and made separate purchases of the gallon jugs because most stores only carry one or two jugs. I think it was 40% off coupon at the time for each sale? Just google "advance auto coupon". It usually gives you a link to the "retailmenot" site and find the highest $ or precentage coupon they have. Usually it's a 30% off or a $25 off a $75 purchase. Once in a while you'll see a $40 off an $80 purchase.
