Do you have some old Tupperware in your cabinets? Start digging. They might be worth SERIOUS CAKE.
Sites like Etsy and eBay have sections dedicated to vintage Tupperware. All kinds of items are up for sale.
You might be able to find matches to old sets; or you could probably make a few bucks, if you want to sell the ones you aren’t using.
Some pieces are selling from $4 to $20. A rare container might be sold for almost $60.
The vintage Tupperware is really popular, because they were made for tiny spaces – which makes the pieces fit in small storage areas. The retro designs and colors are popular, again. Plus, that lettuce or celery/bread keeper reduces the use of plastic zip bags.
