Tupperware is wonderful but expensive.
There are many people who just cannot afford to buy the quality items that Tupperware have to offer
A great CHEAPER way to own Tupperware is to keep your eyes out at Garage Sales and Op Shops for Tupperware.
It really is easy to find Tupperware in good condition at garage / yard sales and thrift stores if you don't mind the less-up-to-date colors!
It's guaranteed forever, so if anything happens through normal use while you own it, then most times it will be replaceable.
Just take them to a Tupperware lady for possible replacement.
If a replacement isn't available, you'll get credit toward new pieces.
When looking at second hand Tupperware, it is best to buy undamaged goods. Always ensure that any cracks, chips etc are from normal use and not from using in a too hot microwave etc
