5. Buy trading pins on eBay.
You can even save money while pin trading in the parks. Before heading to Disney World, purchase pins on eBay that you will trade when you see a Cast Member who has a pin you’ve been looking for. You can buy pins in lots of 25, 50, 100 or more, and many merchants will sell them for around $0.40 each. That means you can trade a very inexpensive pin for one that might complete a collection you have started! Win, win!
