BEWARE. I purchased a groupon for $30 to do my two front windows. After the guy redeemed my voucher, he tried to pressure me into upgrading to a more expensive tint. I told the guy no, I only want what I paid for but he kept insisting, stating the standard tint will have to be replaced I two years. Bottom line, these guys lied. I contacted sun tek and the guy told me that info was false. I'm in the process of getting my money refunded from groupon. I also had my daughter cancel groupon too.
