I try to answer the question: "Is it worth this amount of money for what it does, if it does it perfectly well?". I don't care about marketing and branding, and focus only on the product itself. If the value seems to be too low, I try to improve the product, not the marketing.
I think Tinder does an extremely great job at pricing using age-based segmentation, because that's where the real value of the service defers to the users. It's not that people above 30 can just afford to pay more - they literally can't afford not pay, since they don't have as many options.
