On a whim, I did a quick search and found some interesting beers at Liquor Outlet Wine Cellars. As bizarre as it sounds, you cannot view the site normally and find these beers. You have to copy-and-paste from here and search for them. I checked one of the Schlafly beers and it was in stock, no guarantees on the others.

Here is a short list:
Schlafly Reserve Barleywine 2007
Schlafly Reserve Imperial Stout 2007
Southern Tier Krampus Imperial Helles
Southampton Saison Deluxe 750Ml
Samichlaus
Sly Fox Black Raspberry
Sly Fox Christmas 2008
Cantillon Bruocsella 1900 Grand Cru
