frugalskate 

One who doesn't spend money frivolously.
Different from a cheapskate who refuses to spend money on almost anything.

He's got so much money saved, he's such a frugalskate.

To voice shame or disapproval of someone's extreme act of hoarding or reuse of valueless or disposable items to save money at a detriment to their health, happiness, and time.

I saw Bob pulling a broken fan out of the dumpster. He told me he was going to save it and try to fix it. I had to frugalshame him and remind him a new one that works is literally $10 at the Dollar General.
