had an in house sales pitch with window nation in late march 2011. while its product is very good, the prices are extremely high - almost twice the competition. most of the time was spent trying to convince me other products are basically junk, including newer windows in my house. salesman gave one high price if contract signed that night, and an even higher one good for the next 30 days. though i informed wn rep i was in the process of getting quotes, he was obviously unhappy i would not commit and left quickly after i made that clear. also, the "buy 2 get 2" promo that made me call them in the first place is misleading. you get the hardware for the 4 windows for the high price of two, but then high installation fee is charged for all 4. all in all, would not recommend unless you intend to spend at the very high end of the window scale.
