I feel that Tupperware products outlast any other storage products out on the market today. It's the quality of Tupperware products that brings people back for more.

Just compare the the savings yourself:

If you had to buy a box of 50count sandwich bags @ $1.99 each month for your lunch or a kid's lunch that ends up costing you $23.88 at the end of the year and $119.40 within 5 years. Not only are you wasting money but you're throwing these bags away each time they're used. If you just bought a Sanwich Keeper Set (which comes in a set of 2) for just $11.00 you'll be saving money plus saving the environment ;)
