Query: Try finding a place to return it.

We have had two of these skillets in 6 years. Both over time have gradually developed a brown skim on the cooking surface and become no longer non-stick. We returned the first one and now our second has done the same thing. We have followed the manufacturer's instructions (no cooking on high heat and no dry cooking). And in the last two years we've never found a store that carries this item to replace it.
