If I paid more than the cost of the season for individual episodes, can I complete my season without paying more?

😟 Im afraid you can't, they set up the prices to market to you to buy the whole season because its clearly cheaper. If you have bought enough episodes to pretty much pay for the whole season, they will probably not be like, "Oh okay, the rest is free." No, no, no): That's a choice we all have to make when purchasing tv shows.
