There are some limits on their lifetime replacement policy now. If an item is no longer being made the dealer may be able to get a substitute piece. I just had to return a piece because it discolored. They no longer had the same color of turquoise that I had originally purchased so I accepted a green instead. It does the job.
I went to a unique Tupperware demo back in January where the demo prepped 2 separate meals We paid a flat fee and she supplied the food and the Tupperware. Of course you could by more but everyone got 2 different sets of bowls and a chicken dinner and a pork meal. She also demoed different products and her sales were good from the get go. I don't recall what we paid for the evening out and cooking experience but it was a lot of fun. I think there were 10-12 of us and she did get 2 bookings for the same kind of party.
