I was just searching around and found a good deal through Max Madsen Mitsubishi. When you go on maxmadsen.com pick the location (aurora or countryside) and go to parts dept. then parts coupon. You will see 20% off accessories and 10% off labor, click on that and print it. I went to the one in Aurora and got a cf vortex generator for $198.25 after tax. They had no issue using the coupon and I have been there before and have always had a pretty good experience. Just figured I would pass on the savings!
