Well, you have to realize that you are really just paying for information. What bulbs are needed, what resistors are needed, and install guides. It's not like they make their leds, so that's where the profit is. And that's why i did it myself. Because it isn't hard if you have done some wiring. Plus, certain things i wanted to do differently as well. To me, there prices are pretty reasonable if you are clueless and not willing to try to figure it out. Or don't have the time to.
