I used a living social deal as well. Just got it done and for the price it was great! There are a few bubbles in one of my side windows, however, his tint comes with a life time guarantee so if they do not go away in a few days I'll take it back to them. I didn't wait for them, I dropped the car off and picked it up when it was done which cut out the annoying waiting. I would recommend them if you want your windows tinted for a cheap price. They offer upgrades to 20% and 5% too for living social deals, and he did 2 extra windows for me pretty cheap!
Update bubbles went away. The tint is 100% perfect and we could not be happier with it!
