Not quite $240, but Netflix apparently spends about $100 for customer acquisition [1] (data is a few years old). I imagine the other streaming sites have similar unit economics.

In consumer finance, CACs are even higher. For standard credit cards it’s around $200 but can be over $1000 for premium cards.
