In my quest to broaden my palate in the beer world I've found myself branching out past the usual suspects that are available on draft locally. I'm lucky to live in an area with some great bottle shops, but sometimes they just can't get something due to limited distribution or low production. There are so many small production breweries in the US that it's sometimes very hard to find certain bottles.

What are your favorite mail order shops?

Also: if anyone has a bottle (or a source) for Founders Kentucky Breakfast Stout, I'm actively looking (I know I'm late to the party.) Thanks!
