Looks like they a giving ~ %10-15 discount on the MF and passing on the labor cost. Reasonable from a dealer IMO.
If you don't have a jack and not prepared to take the tire off you will find it challenging to install the flaps, especially the rear.
I mail ordered mine and installed them myself... I also went the extra step of having them painted which IMO makes the car more appealing.
