Princess Pumpkin...
I can tell you how I started my son in pin trading last fall...I went onto E-Bay and bid on/purchased some pins for him there. Once I got started...it was hard to stop! Some of the pins are so neat! I ended up with about 20 pins before we left for Orlando. Also, once we got there, I let him pick a few pins from the Pin Traders store at Downtown Disney, along with a lanyard to put them on. Then, we just started collecting them along our vacation/cruise. He only ended up trading a few, and I think he has decided that he will collect pins and maybe do just a few trades here and there. Hope that helps...
