Most ARE being used actually. Except for the odd few that I bought just because people were clearing stocks at a good price. Also, Tupperware tend to come in sets (of 3, 4, 5 pieces) so sometimes I don't use every single piece. But hubby is pretty good at helping himself to them too!
I do get so happy shopping for, buying, receiving and using these colourful things. :)
These are all our Mummy's tupperware
But this one is my milk bottle. *gulp*
