Some people care about how reasonable a price seems even if they can easily afford something, because it's important to them to feel like they're getting a good deal or at least not getting taken advantage of. They're happy to accept some level of inconvenience or discomfort if the savings are big enough, even if they don't particularly need the money Some people care more about getting exactly the right thing, even if the value proposition is weaker. They'll pay significantly more for apparently trivial differences, because they don't want to buy something they're not happy with; they're spending money anyway and why put up with something they don't want if they can afford something they do want? Neither of these people are strictly unreasonable.
