The rest of the windows will probably cost you at least $60, but then again, it is probably relative to the cost of the tint you will be putting on too. I had them install Formula 1 tint, which is supposed to be the best on the market. The Llumar is the next step down, and I am not sure on the options below that.

Down here, most cars are about 180 with the Llumar, and about 230 with the Formula 1. Of course, there are the guys that do it for $45 all day, but it's the crap that turns purple.
