I would never be able to use just one soap lol. My collection (museum) of soaps is way too vast to be able to whittle it down to just one, even if i was to share everyone on the block could shave for life hahaha which is probably a true statement. Enjoy the variety WAY too much and treat shaving as a hobby but can understand many people do use just a single soap at a time then purchase another once it runs out. We are all different and whatever makes you happy is the right choice IMO.
