Chevron station at Dairy Ashford and Harwin (Alief Clodine) gives $5 off. Same for a shop at the corner of Wilcrest and Harwin (across from the Shell gas station) or garage shop at Beechnut and Kirkwood.
Not a guarantee but if you've been a customer of Firestone Auto Service center in the past, they will send you special promo coupon (last year they sent me a $5 off any service, State Inspection included coupon but not this year). So a hit-n-miss at best.
