Just thought I'd point out that Auggie's games (a minis store which mostly sells prepainted figures) is now selling Descent stuff, too. They're out of dice at the moment. (That's my fault, I'm afraid.) But there are still lots of corridors, figures, and such in stock.

No, I don't work there, and I don't get anything for pointing people to the store. But I've been happy with the store for other miniatures, and it seems like a good resource to me.
