^^^^Wow man, I mostly do this for fun. Yea the money side of it is nice, but what you just described does not sound fun at all, and why would I want to spend my time doing that? I might as well just get myself a shitty job. No thank you, I'm going to keep my sanity and low blood pressure.
edit: and to each his own. You are free to thrift how you want, this is Merica' after all, you keep doin' you.
