For years, my family has found all the gift with purchase pins easily on cast lanyards, and just traded for them. But this set has been nearly impossible to find! They are RARELY on cast lanyards. Is it because this is a Haunted Mansion set, and so it is more popular and people don't want to trade the pins away? Is it because they upped the price you have to pay to get the GWP pin to $25, so there are fewer out there?
