I can't parse what you're saying. Are you saying the quote I replied to is correct?

In any case, I think always is close enough to fit. Yes, sometimes someone gets something very cheaply but that's usually because of ignorance or urgency from the selling party, deception, etc., etc. In a natural market interaction, if you're paying bottom dollar you are not and cannot be getting the best quality (unless you are in a scenario where the offering is flat: the best offering is also the worst).
