Query: Poorly constructed

I bought this special anniversary edition from Amazon for $30.00 and was extremely happy that I found such a pan for this low price. I have 20 pieces of calphalon and 6 of those are commercial nonstick. This piece was horrible. I never use it for high temp cooking and absolutely never use metal utensils, but within 6 mos it was chipping and pitted. I was not going to pay to ship it back to Calphalon when shipping would be a sizeable percentage of the cost of the pan, but I had to stop using it. All-Clad for me now, thanks.
