Wanted to use them since they are close to home and had an "accept most coupons" sign in front. Asked if they would accept one from a competitor, showed him the coupon and was told yes. After the smog check was done, was told that they could only take $2.00 off and couldn't honor the $16.00 price on the coupon. Then pointed to the $1.00 surcharge fee for debit/credit cards. So I am now $1.99 over what I initially thought I was going to be charged. After seeing other reviews on here, apparently I am not the only one to fall for their slick business practice. No, Smog Hut, I don't want anyone to contact me to discuss my $2.00. Just want others to know what they are getting into if they use use services.
