Fog Light suggestion?

So I am purchasing a new car at the end of Nov when I reach my savings goal! Mazda has released the 'Build your model' with the skyactiv feature, and I was toying around with it. One option that was given was fog lights, for 350. I enjoy the look of the fog lights, so I do want them at some point, but I was wondering what suggestions y'all had about them. Whether to allow the dealer price, or to just put them in later myself.
