Nope, loulou, you're not the only one! :wink:
I don't collect pins either.
For some reason, however, I do own 4 Disney pins - and one of those is traded. You see, when I stayed in WDW (in 2001), both my mum and I received a complimentary pin (Mickey as band leader). My mum gave me hers, so I traded my spare one for a pin of the beautiful castle.
The other two pins I own, were gifts. A Lilo&Stitch one, and a Big Thunder Mountain one (because I was so brave to ride it :wink: ).
I, for one, really don't get the pin trading craze.... Sorry guys!
