My X was a cheapskate. That's one reason he's an X! He wouldn't spend money on pest control, and we lived in Florida, so we had a roach problem (we were clean - roaches are a fact of life there). I finally had enough, and he grudgingly gave in.
He could also be cruel with his cheapness. One time I was out antiquing with my mom and sister - we were on vacation. I spent $25 on a pretty Victorian bowl. He was very upset with me. His words: "I was going to buy you something, but since you spent that money, now I'm not." Just one more nail in the coffin.
FTR, he's made well into 6-figures for almost 30 yrs.
