The only thing you have to consider when buying tint off a seller anywhere is the quality. Yes you may be able to buy enough tint to do your car for 30-50$ but what about all the time you spent crampped in your car just to have the tint discolor in a few months or have the adhesive go to crap. Most places in the U.S. charge alot but thier work is warrantied for a amount of time. I put some tint on my front parking lights and from far away it looks good but the tint has started to crack and bubble up. This is after they were cleaned and applied with a heat gun and looked showroom great when installed. I want to go with some VHT but then I think I will just eliminate them completely and put them in the headlight housings instead and color match the parking lights.
