Bought through Groupon. Never again. Please read the fine print. Called and got first appointment scheduled easily before they knew I had coupon. Bought for my college age son, but unfortunately he had a telephone interview that day and I had to cancel. Tried so many times after that, like 6 or 7 to reschedule, but they were too busy (overbooked due to Groupon). Well, he went back to college with no tinting. Deal only good 120 days, but they so over booked we couldn't get in. So called deal good for 120 days. Guess who loses? Never again Groupon or SunBlockers.
