I love Wm Neumann Old Fashioned Soda shaving cream. I believe it will be my first software product that I actually finish, even though it's a huge 8oz jug. Mantic59, The Sharpologist, named it as one of the six shaving products he doesn't want to live without. The flavor is more root beer/sarsaparilla than Dr. Pepper, but it's clearly an old fashioned soda scent. By the way, an 8oz jug lasts a very LONG time, and I'm convinced the cost per shave is meager. The quality of the lather is awesome, as well, in my experience.
