If you want to buy pins from eBay, make sure you do your research. Many sellers are selling pins for around $1, which most likely, they will be scrappers (pins you can't trade at Disney). Other sellers I have seen have authentic pins for sale. Sometimes, it's best to buy booster sets, not the big pin lots. Make sure you are looking at neutral and negative feedback on eBay because a lot of scrapper sellers have pretty good feedback ratings. The reason for that is that most people do not know that these pins they are getting are scrappers, so they leave good feedback. If you look at neutral and negative feedback, and a customer suspects that some pins are scrappers, it is best to stay away from those sellers.
