DOOM Expansion Set available New from boardgames.ca

[Frog 1]

You can get the rare DOOM Expansion Set for $59.95 canadian which is basically the same price in USD.

With shipping to the US this will run you about $77.  Which is far cheaper than Ebay, Amazon, or Boardgamegeek.

Unless you know of one sitting on a local FLGS shelf, this is the best price i have seen in about 4 months.

And it is legit because that is where I got mine.
