Tinder is so extremely effective that it's almost certainly underpriced at all of these levels purely because of perception. I only had gold once and bought a couple of boosts but for over two months I would fill my calendar with 2-4 dates a week at something close to Spotify sub ($20/mo iirc).
There is no other way to meet women this efficiently. And it was a lot of fun, too. It took out all the slog out of dating. It would be a steal at $100/mo.
