I have been waiting for months to receive my discount check for windows that I purchased via Lowes by Milgard. I have sent several message to the corporate office and nothing. I had the chance and choice of other vendors but I chose Milgard based upon information that I read, recommendations from consumer reports on 3 pane windows and their guarantee. Also the discount would save me several hundred dollars on 20K in vinyl windows. To this date, nothing.
