Your Grandma's Old Tupperware Might Actually Be Worth Money
You probably know the old adage "what's old is new again," but did you know there's actually a market for vintage tupperware on sites like Etsy and eBay? Turns out, some pieces can retail for quite a bit of money (though you probably won't make as much off them as you would selling your vintage Pyrex.)
Select sets from Tupperware's Wonderlier line or Servalier line could retail for hundreds of dollars. Other vintage Tupperware pieces typically sell online for $2 to $20 each, but could be more, depending on the condition and age of the items.
