Should have read reviews before making the mistake of coming here. Rip off!!! Do not come here. With a competitor coupon, they still charge $18 at the lowest. Then when you go to pay, they slap on another $6 to put it into the DMV system without telling you. Why would anyone get a smog test besides to register their car?!? So the lowest you will pay is $24!!! Then if you're too lazy to find a DMV kiosk (there's one right inside the Albertsons at Trop & Jones), you can pay  $10 more for them to register it for you.
