I first went to their location in the parking lot right across the street. The guy there said "I'm out of smogs right now" and directed me across the street here. I've used both Smog Hut locations over the years and had hit and miss experiences as far as coupons go and them being "out of smogs" LOL! So I went to the location across the street and there was a line of 5 cars ahead of me. I will say the guy got the vehicles through in good time including my car. I checked in on yelp while waiting my turn and was happy to see a yelp deal that would get my smog for $15 instead of the $18.99 regular price. When I showed it to the guy who did the smog he got sort of an attitude and said that he wouldn't honor the yelp deal or any coupon and the most he could give anybody off is $2 max and only if they asked while trying to use a coupon. If they don't want people to use any sort of deal then they should remove the yelp deal and remove all the banners and signs they have posted saying that they will honor any coupon. That's just bad business to advertise that you will honor any coupon and then not do it.
