I'm not sure, Mike, but I'm gonna guess that since Camillo's in Oregon, it must stand for something like Oregon Liquor Control Commission or something like that.
As you know, in Washington it's the WSLCB (Washington State Liquor Control Board), so I think it's just the state-run liquor store.
You should be able to just walk on in to any liquor store and ask for it by name. If they give you the "Huh?" look, tell them it's a French liqueur, it's clear, and it smells and tastes like licorice. It's a lot like Uzo and Sambucca.
