I just have fun trading. Will trade with a Cast Member (CM) or kids for pin even if it is not one I looking to get, just to trade. I used to be very specific until I noticed some of the CMs looked disappointed I didn't trade with them. Sometimes I get scrappers, other times I get real pins. If I can tell it is a scrap pin, I'll see if family/friends want it, if not I toss it in the trash. Drives my wife nuts when I get in a trading mood. She wants to go somewhere and I just disappear chasing a pin. Just so you know, not all CMs trade. If they do, they will either have a lanyard or a hip lanyard. One note, if their lanyard is green they will only trade with kids!
