Stores with shiitake mushrooms?

Libertyville IL

Description

I'm a stir fry enthusiast, and one of my favorite combos is green bell peppers and shiitake mushrooms with some teriyaki sauce (Cowboy Bebop's 'bell peppers and beef' recipe). But it seems whenever I go to the store (I usually go to either of the Jewel-Oscos in Mundelein), there's hardly any shiitake mushrooms left. I'm stuck with using white mushrooms, and they just don't compare. Any other stores in the area that I might have more luck with?
