Department stores throughout the United States sell Corelle dinnerware, but there is no official time table as to when the items go on sale or clearance. Corelle and Corning outlet stores have many items at discounted prices year round, including discontinued patterns.
Corning Glass Works introduced Corelle dishware in 1970, and it became popular because of its versatility and style. The vitrelle technology of bonding the layers of glass makes Corelle exceptionally strong, durable and lightweight. Although it is made of glass, it is break and chip-resistant.
World Kitchen later purchased the Corelle and Corning companies, and many of the original patterns were retired. Retired patterns and pieces are still widely available at Corelle outlet stores and online sites such as Replacements.com. Current sets and open stock items are available from Corelle.com, which frequently offers discounts on the purchase of multiple items.
WorldKitchen.com also offers frequent discounts and sales on Corelle items with free shipping for $99 orders as of 2015. Shoppers who sign up for its email list receive notifications about current promotions, product news or events. The website also offers a link to find a nearby store. World Kitchen also owns and sells Corning, Snapware, Pyrex, Chicago Cutlery and Baker's Secret brand items.
