Yes, I have to admit that I am an avid Tupperware fan. Many years ago my sister put herself through college selling Tupperware and I - being the good older sister that I am - must have been her best customer. But I've been a fan ever since. I have never bought a bad Tupperware container and some of mine are now over 20 years old and still in perfect condition.
They come up with all kinds of little gadgets, gizmos and such as well, and those are fine - but the old classics are the best. And just because an item is called - for instance - a shaker - it does not mean that you could not put pickles in it. This is something my sister told me a long time ago and I've headed her advice - my Tupperware gets tons of use!
