I had the same problem with them when I ordered insulated garage doors. I made sure to have them shipped to the store, instead of my house (which was free). I looked at them at the store and they were bent up. They offered me a significant discount; however, my buddy said there was no way to fix them (he used to install them). I got my money back. Costco installed & now the shop stays toasty when the 220v heater is on.
