Yes, it's true that Tupperware products have a lifetime guarantee.
They will replace any cracked or chipped item at no cost to you. Well...
...if you're willing to pay $4 in shipping to get a small rectangular lid replaced, that is.
The lid, about the size of a standard envelope, won't cost that much to ship. I guess it just costs a lot to "handle".
Thanks, Tupperware, but I think I'll pass. Just direct me to the nearest yard sale instead.
If you have damaged Tupperware and would like to cash in on its lifetime guarantee, phone 1-800-366-3800.
Note: I have had a lot of success "de-greasing" sticky Tupperware with a mild ammonia rinse.
