A great many of their things are now "obsolete". If it needs replacing, you will get credit for the item. As in my sugar bowl and seal, which cost $.79 in 1951. That's when Tupperware started. They still give you credit if it is cracked, broken, chipped or peeling.
But a warped seal (yes, they are called seals, not lids) may or may not be replaceable. Depends on your distributorship.
Sometimes the old stuff comes back for special promotions or seasonal. Like the fix 'n' mix bowl. It's been for sale every once in a while. While it is for sale is the time to get it or its seal replaced.
