Kmart, Target and Wal-Mart all have Corelle dinnerware sets on clearance. These stores not only have the items at a lower price that some high-end retailers, but they frequently have sales and markdowns.
Kmart is one of the more affordable retailers that sells Corelle dinnerware sets. Look for the sets that are available at a local Kmart by setting the location with a ZIP code.

Target also has multiple sorting options, including by material, color, type, diameter or height of bowls or plates, and by price range. To find discounted dinnerware at Wal-Mart, go to the Corelle page, then look for the word Rollback near the picture.
