Curtains and shirts that come with an acre of cardboard and 300 plastic pins, then wrapped in thick plastic.
I bought a Little Tykes rocking crocodile garden toy from Toys R Us last year. It's just one solid toy, no assembly required, no bits or anything, just a one piece big toy. So why did it come in a humungous cardboard box? That was stapled together? I had to unwrap the bloody thing to get it in the boot - the cardboard box added an extra foot to it - so I dumped it in the foyer of TRU. Have to say that my fingers were firmly crossed that I wouldn't have to return it for any reason, but I just couldn't have got it home with the box intact.
Stupid, stupid, stupid to put so much packaging on.
