Purchased an AC recharge service that the Groupon specified as "up to 1lb of freon" to drive to the location and find they won't honor it because it's the expensive type of Freon not the regular 134. Even though there's no print anywhere suggesting that it has to be one type or another User's recommendation: Don't attend Kwik Kar if they're going to cheapskate or skim off the top of service's they claim to offer.
