Why board game expansion pricing is volatile
Board game expansion pricing on out-of-print expansions, Kickstarter exclusives, and limited releases varies dramatically across BoardGameGeek Marketplace, eBay, Noble Knight Games, and brand-direct. For out-of-print Twilight Imperium 4 expansions or Gloomhaven Forgotten Circles, aftermarket pricing can range $50 to $300 for the same item.
