I worked at Kohls over the summer, and my buddy said that we were a test store for this kinda stuff. Normally they are not supposed to allow you to use discounts on electronics, so it really depends on the management at the store.
I got the 500 points, but you get 500 if you get Second Son through Gamestop, which I am, so that will put me over 1000 so I can just get a $10 code instead.
I saw an article somewhere that someone got the DS4 to work with the 360, which I found silly, but interesting. I'm wondering if when we get closer to launch if they will release more drivers for the controller so we don't need the third party software?
