I want to trade Pandemic (with On The Brink expansion) FIRST edition for Pandemic SECOND edition + $20. The On The Brink expansion (second edition) currently sells for $50 new on amazon. I never use the expansion, which is why I want to sell it. However, I do not have the box for it and it is currently placed in the base game's box. I am also willing to sell just the expansion for $25. Please contact me if you are interested.
