My kids love to trade pins too. They have gotten a couple from CM in suits that were only given to CM. I never knew you could get them off e-bay or at stores. I will have to look. They especially like getting special ones, like from our resort or Star Wars Weekend ones. My older boys are 10 and 8 and they don't like the lanyard that goes around your neck. The first year we went, I got them the lanyards and they said it was itchy and made them hot. I took them back and let them pick out a hat. They put their pins on their hats and have gotten lots of comments on their hats.
