Typical clip joint. Had a coupon for a $39 front end alignment. They charged me $49 because they had to do "4 wheels." No offset for the adjustments they did not do on the vehicle. Kiind of like the lube oil filter places, no discount because there are no zerks on my car.
These places have a page full of coupons in the paper, and a mouthful of excuses why they don't charge the coupon price.
