Just getting into this. Dunwich Legacy is sold out everyplace I been. None of the stores know when they are getting any back in stock. Under upcoming its listed as in stores now.
How can no one know when more will be coming? Very frustrating.
I know I can get it online, but at jacked up prices.
Where are you located? A bunch of stores near me got a restock this past week.
Massachusetts south shore
found a place online they had 2 left. I got 1. 
Which store please?
Ken, do you talk to Battleground Games in Abington at all? I've been preordering everything through them and so far haven't been disappointed. They had a bazillion copies of Essex county express last I was there.
I do talk to them alot. Both locations said they did'nt have Dunwich legacy and did'nt know when more would be coming. I have seen Essex county there. But I don't have the base game yet, I want Dunwich for the extra investigators, The store is really good though.
I found it on Miniature Market. But I got an email saying it was a warehouse error and they were not in stock but they told me it was confirmed that they are getting more in in the next couple of days. So I had them hold my order and will be shipped then. No worries.
It's really frustrating because I have The Dunwich Legacy "big box", but can't find the first chapter pack The Miskatonik Museum anywhere. I'm pretty much stuck in the story line until I can find it somewhere.
In case you are in Germany (or have friends who are). It is available (in the English version) here
Yeah, it's really frustrating. I like the game, but this is getting really old, really fast.
It'll end when the cycle ends. Their predictions were way too conservative for the popularity of the game. By the time Lost in time and Space comes o7t most of the set will already be reprinted and the next set will be ordered in about 3x the number. Things will improve.
This may be helpful, or infuriating, but I keep seeing Miskatonic Museum on shelves in gaming shops in the U.K. Apologies if that's of little use to you, though!
Team covenant has the Miskatonic Museum in stock.
