I have a coupon for a $9.99 oil change. Don't believe these coupons! My van does not require the cartridge filter or skid plate and it still would of cost $18.00 then after I left I seen a big sign permanently advertising a $13.95 oil change.... There are too many hidden fees. Like the minimum $4.00 labor? Then guess what perfect auto you should factor this into your "coupon price"!! But this would hinder your bait and switch pricing scam you have going on.... I'll be deleting the app and I won't be back! Enjoy the bad reviews and bad way of advertising a" special"
