I know some people with similar stories. The frugality ends up being a cause for purchasing too much cheap stuff, with the hopes that "the next" will be as good as something top-shelf. Or it's stuff for their DIY project. The reality is that they don't need any of those things, it's just aspirational. Throwing them away kills the aspiration.

I know some quasi-hoarders who are similar, too: I know a person who has 30 guitars but they're so cheap and badly maintained that they're probably less worth than a high-end one. And the "next guitar" they buy is only good for a couple days.
