Where can I buy one dinnerplate Corelle Hearhstone, Square shape, Chili Red color?

If you phone the company they will probably replace it for free. Or even if you go to the store where it was purchased they might replace it. Corelle is in a group of companies called World Kitchen: http://www.worldkitchen.com/ Depending on where you are, I think this site is for North America only. I have phoned there before and they have sent replacements, even years later.

I hope this helps.
