Hot Sauce Lovers?

Any recommendations for some shops for decent hot sauces around the area? King Soopers and Safeway tend to have a sprinkling of decent brands here and there (Hellfire, Torchbearer, etc.), but not a wide selection. World Market has a little better selection, but still not a big selection.

I usually end up just ordering online, but would prefer a shop where I can sample stuff.

So, any pepperheads around here know a shop?
