We replaced our old (1979) Corelle set with new ones. We needed extra plates and lunch size plates (which were included in our old set, but not in the new set). The price was good and delivery prompt. Our only complaint is that the quality control seems to have gone down hill since World Kitchens has taken over the Corelle line from Corning. Several of the new plates are warped (more that I would like to see) compared with our old plates, but they are still usable.
