Some woodworkers use it, so an Ace or True Value might have it (heck, one of the 'Box Stores' might have it too, but I have to wonder what would actually be in the bottle).
I've heard people that are into wooden boats use it as well, so maybe at a marine store?
Just make sure to store any rags that you use with it somewhere safe (ie, if they spontaneously ignite, which supposedly can happen, they won't burn the shop / house down).
