PLV isn't just the sticker price - it's the total cost of ownership when considered against the utility and convenience it provides.
I no longer set a goal to find the very best #1 thing in every category by reading reviews when I'm buying something. Reviews can be hit or miss, anyway. Instead, I focus my energy on getting good value and buying the best when it comes to things that make me happy or I use a lot.
A computer monitor is a great example of something where PLV for a developer is totally different than a casual user, but the equation serves them both well in pre-purchase considerations.
