I did this about 3 yrs ago and "won" a small amount which I think this is actually a everyone wins and sales pitch kind of thing.
I still had to pay a bit but it was ok, I liked it but do note that you will have to pay some cash BUT they also do pmt plans which was nice. I didn't get it completed (you have more than one visit) as I had an accident that ended up putting me out of work and I am still in deep water in many many ways so to speak (disability now) but this place, the people and all were A ok.
