Nowadays you can go into any store and buy stuff that is similar to Tupperware and it's usually cheaper.  But, you wont get the quality that you'll get through buying actual Tupperware.  I mean, think about it!  Tupperware started the craze of storing everything from crayons to leftovers in plastic containers!  They're the brains behind it all, and they're the ones that have a leg up on everyone else.  Their products are above and beyond all other products that try to be like them.

Tupperware. products carry either a Full Lifetime Warranty or a Quality Guarantee, which is awesome because they stand behind every product they sell. For over 50 years, the Full Lifetime Warranty has provided customers with the knowledge that Tupperware brand products are the finest products available. The Quality Guarantee provides customers with the additional assurance that any product sold by Tupperware will meet standards for quality and superiority.

Tupperware. products are guaranteed by Tupperware against chipping, cracking, breaking or peeling under normal non-commercial use for the lifetime of the product. If you do have a problem you can call their Customer Care department toll-free at 1(800) 366-3800 or your local consultant for a free replacement. If, due to unavailability, actual product replacement cannot be made, comparable product replacement will be made, or credit toward future purchases of Tupperware. products will be given. Warranty replacement items or parts will be free but there are shipping and handling charges, typically you can warranty a bunch of parts or items and the shipping cost will stay the same as if you had only warrantied 1.

So you see, with Tupperware you do get more bang for your buck!  Can Rubbermaid say they will do the same?
