How much does MUBI cost per month?

Could you please provide some clarification on the pricing structure of MUBI? Specifically, I'm wondering what the monthly cost is for accessing their platform and the various features they offer. Is there a flat rate for all users, or does the cost vary depending on certain factors? Additionally, are there any discounts or promotions available for new subscribers? I'm keen to learn more about the financial aspect of MUBI before making a decision.
