i like tupperware warranty. although limited, already change a couple of cracked tupperware to new ones

Just bring your broken tupperware to their shop. If still in production you can basically exchange it for free. Else they will tell you the value of your broken tupperware and you can choose certain model as replacement. If the chosen one is more expensive then need to top up a bit.

I exchanged my water bottle cover few times d.
