Those last three things you mentioned are exempt...It is a hobby to some, (well MANY here LOL) and hobbies tend to cost giant piles of money. If all you want is a shave you can get it on the cheap. As long as you aren't forsaking food or your children's healthcare for it it is no one's business but your own. I am down to a very simple shave setup and PIF'd my meager collection of razors so others could enjoy them. We will not discuss my guitars or guns or tools of course!
