Kirkland Stainless Pots and Pans - warped (4,546 views)

What a shame! They look lovely, too. Costco seems to be quite liberal about their return policy so I'd certainly go that route.
I've not had that happen exactly, but I did have something weird happen to one of my older pieces of Cuisinart stainless. I believe I'd purchased the piece back in the early eighties. It was one of the few pieces I really didn't abuse in some way (I do not treat my cookware with kid gloves, sorry to say.) One day, my husband pointed out that the metal disk on the bottom of a large saucepan was starting to separate from the body of the pan. Would you consider that a form of warpage? I emailed the company, was told to send it back to them and if they determined I'd done nothing wrong, they'd replace it. Shortly thereafter, I received a new pot and lid. It's not exactly what I had before, but the product line I'd purchased was no longer being manufactured. I was fine with the substitution so all ended well.

I would THINK that since the item was only available as a set that they would offer you the option of either replacing the entire set or giving you a refund. I'd be surprised, actually, if they don't.
I once felt silly about returning some meat to them (who returns meat, right?) I'd purchased it, bought it home and the next day it turned a disturbing color. They could've questioned me up and down as to how it was transported or stored, but nope. They gave me a refund, no questions asked.

I recently looked on their web site because I'd purchased a book, brought it home and discovered I'd already gotten that one. The web site seems to imply that if you don't like something, you can bring it back at any time.

I am very much an anti-return person. It takes a lot for me to decide to return or exchange something and I hardly ever do it.

That being said, I've done returns at Costco. Wow! No receipt required, no real questions asked, if you aren't fully satisfied they believe you are right to return an item. Earlier this year they had a bunch of recalls on frozen fruits and vegetables. They looked up my account and refunded me for every bag that I'd bought during a certain period of time. I didn't have to take the product in or anything. I was amazed.

I would take the set of pans back. Did you use all the pieces in the set? You might be better off going someplace where you can buy just the pans you will use. I know with sets there are always pieces I seldom use and wish I didn't have taking up space.
