How the Competitor Coupon Match Works
This is a separate offer from our $5.00 coupon above. Choose one coupon and use the discounts you qualify for.
Got a smog check coupon from another shop? Bring it to Smog Busters and we will match it. Any local competitor coupon is accepted for up to $5 off your smog check.
Here is how it works:
- Bring any local competitor’s smog check coupon. Print it out or show it on your phone.
- Present it to the tech before the test begins. The coupon must be shown before the smog check starts.
- We match it for up to $5 off. The discount is applied to your smog check on the spot.
It does not matter which competitor issued the coupon. If it is a local smog check coupon, we accept it. No fine print, no runaround. Just savings.
Seniors and Heroes Discount
Smog Busters offers $3 off every smog check for seniors, active military, veterans, and first responders. We call it the Seniors and Heroes Discount because these groups have earned it.
The best part: this discount stacks with the competitor coupon match. Bring in a competitor coupon (up to $5 off) and show your qualifying status for the Seniors and Heroes Discount ($3 off). That is up to $8 total savings on your smog check.
We Accept Any
Competitor’s Coupon

Diesel Smog Check
Drive a diesel? Our E. Sahara location is the only Smog Busters station equipped for diesel emissions testing. The competitor coupon match and Seniors and Heroes Discount both apply to diesel smog checks.
