Honolulu, HI
I went in for an A/C recharge and systems check, and I had a coupon for $130. Unfortunately, when I got there the technician told me that my car had a newer type of freon and that the cost would be $450 to do the check. I had transportation arranged so I went ahead with it. In retrospect, I'm a little angry because when I booked my appointment with my auto's make and model, they should have determined that the A/C price was not going to be valid so I wouldn't be sticker shocked like that. So I got mixed feelings over the whole thing.
