Not a small business, but, Costco was carrying "Chicago mix" in a huge bag before Christmas. Not sure if it is a normal/regular item but worth checking out.
Found this pic of the bag via google
I saw a smaller bag of the same popcorn at a Fortino's too (should be at other "Loblaws" stores probably.
If you haven't had chicago mix before it is a mix between cheese flavoured and caramel flavoured. Actually a pretty good combo!
Also, the Indiana brand has a bunch of interesting flavours..
They definitely carry it at Whole Foods but I have seen it at other grocery stores as well.
