Exactly. Value is, to a certain extent, subjective; a commodity is worth whatever someone is willing to pay for it. It's okay to overspend a little to get what you really want, as long as you balance that by being somewhat frugal on things where, for your purposes, the more costly version isn't significantly better than the less expensive one.
e.g., I'll spend extra money on quality craft beers, but I'm cool with middle-of-the-road wines and liquors.
