I'll wear cheaper shoes for certain outfits au something, but my everyday shoes have to be handmade, genuine leather boots. I've had my favourite boots for around 4 years now, and they've still got a lot of life left in them.
Art supplies are expensive in general. At least, the good stuff. I'll buy cheap stuff for practice, but if I want to get serious I'll buy something zaidi expensive.
I'm also not a shabiki of cheap-feeling paper. I always have to feel paper before I buy it to make sure it at least feels like quality material.
Computers. I technically don't spend near as much on a quality computer as a lot of people do, but that's mostly because I'm buying the parts and assembling it myself. Even so,I spent about $1000 on my current model, but I built a computer that would cost nearly twice as much pre-made.
