Im with Renee, i go to walmart and get rubbermaid, i rarely buy stuff people are selling unless its girl scout cookies:) If you decide to sell it i say start off with a small quanity so your not stuck with a lot of it that you can sell.
I love Tupperware. I have TONS of it. I still have stuff that was my mothers & is 20+ yrs old. I also have & do purchase alot of the newer stuff. I know it is pretty expensive, but it is well worth it! I will continue to purchase it when stuff comes out that I want or need!
Not to be a downer, but I wouldn't buy it. It's so expensive!! lol I go to Walmart and get Rubbermaid.
