LorAnn oils are carried (in tiny, rectangular, glass bottles) in many stores and groceries during holiday times--usually in the baking and candy-making section. They also have a website:

Many of their flavorants can be used in single-drop quantities added to a couple of ounces of an alcohol (like Canadian Whiskey--e.g. Seagram's VO or Canadian Club), and sprayed onto shredded tobacco, as a non-sticky casing for aromatic pipe blends.
[As an aside, the LorAnn Clove Oil is natural eugenol, and is miraculous at quelling the pain of a toothache, by dipping a Q-tip (cotton swab on a stick) into the oil, then painting it onto the offending tooth.]
