I'm thinking of words like fiscal, astute, shrewd, thrifty or business-savvy.
However, I know there's got to be a better word for someone who looks for great deals, a person who understands price and finds great value.
For example, a man believes his computer is not working fast anymore. He looks up prices for a new computer, costing $1200. Instead, he researches that his computer needs more memory. Rather than buying a new $1200 computer, he installs $20 of memory to make his computer work smoothly. This man is [deal oriented].
Anything along the lines of extreme financially savvy-ness is great. Another way to think about it is someone who can create something from nothing, or can do a lot with very little.
Any suggestions are greatly appreciated.
