MK Sound pricing- is this good?

I recently began a new position in IT sales. My company works with a local distributor and my employee pricing on MK Sound products seems to be quite low. I have seen retail prices available on the web, but wouldn't expect that is what people are truly paying. My prices appear to be around 40% below.

The S-150's run about $675 each
The SS-150's run about $900/pair
The MX350 sub is about $1300.00

Are these good prices? I already own a nice KEF setup but would want this for a dedicated HT setup. What do you think?

My apologies. I was just trying to get a sense of what MSRP price point folks would find out there. I'm not much familiar with MK as a brand, other than some of their own information on the website. It seems to me, they have a rich history and an impressive list of clients that utilize their professional grade line. I'm looking forward to giving their S150 and S750 lines a listen.
