One of my very expensive, large Calphalon skillets lost some of it's non-stick coating a while back, and GB encouraged me to find their website and see what they would do about it. On the website, I was given a toll-free number, which I called, and I was told to send the skillet to an address they provided. It cost about $8 to mail, but the skillet cost $200.
It's been a couple of months, and I'd been wondering when I would hear from them.
Today, UPS brought me a brand new replacement skillet!
One more reason it pays to buy good pots and pans.
