Don't fall for the Jiffy Smog coupon on the Internet. It's not worth a penny. The company just wants your i.p. address to send you junk mail; in return you get nothing .. nada, for the coupon you present and are told by the technician, unfortunately you must pay the full price for the smog. What gives? We are all suckers to patronize this company that is all smoke and mirrors. I will never use them again. Buyer beware. I just couldn't believe it when the tech charged me the full price for the smog certificate for an almost brand new car. What a racket!
