I have had some fun experiences with the Jawas. Both times I have traded pins that I either had extras of or just didn't want. One of those was a Star Wars pin, and I received a Star Wars pin that I didn't have in return. It was kinda funny, because I couldn't find the pin in my backpack, and the Jawa began to tap it's toes and get really impatient. it was really funny, but the pin made it totally worth it that I received. I haven't tried trading anything else, but I might do that for my December trip.
