I too went to Home Depot and was turned away by ignorant but nice sales people. I then contacted the manufacturer (Premier Industries/Insulfoam West Coast), and the Home Depot rep happened to be onsite, and I talked to him directly. When I told him the run around people were getting at Home Depot, he was shocked. He called my area Home Depot directly, and I ordered the kit for approx $37. The current SKU is 481-957. The url for the manuf. is http://www.insulfoam.com/. The rep said that there should be a Insulfoam book at the pro desk and there is a brochure on the garage door kit in it.
