Shoes and kitchen knives, I guess. I spend most of my life on my feet with a knife in my hand. Birks only for the feet. Can't do anything else. Not an expensive snob on the knives, but I can't deal with ####ty, dull knives. Luckily Victorinox is rather cheap. A Victorinox sharpened on a whetstone and properly steeled and maintained (no cheap steels either) is a must for me.
Cookware too, I guess. Luckily, you can be a cheap snob there too because cast iron exists. When I'm at someone's house, I always have the urge to go through their kitchen and throw out all their crappy knives and non-stick cookware and leave them with well season CIS, a sharp knife, and the right cutting board for their needs.
Also a cheap snob about whiskey. Price doesn't matter, but I refuse to buy 80 proof whiskey. I can't believe people spend money on that #### when there is such a plentiful supply of cheap, delicious 86 to 100 to barrel proof bourbon and rye out there these days.
