If I were inclined to make my own aftershave, where could I get menthol crystals? I know they can be bought on the innerwebs, but I hate to spend $8 for the crystals and $8 for shipping. (An $8 quantity would last practically forever - I don't need a pound.) I live in a big city (Houston), and every place I have tried looks at me funny.
Any thoughts, or is the web my only option?
And also, what about glycerin? I am thinking that would be easier to find, but I haven't looked yet. Drug store?
