Buying TV shows

I have a problem/question regarding buying a TV show that I had already purchased, that I would like to buy as a gift for someone else. I have a TV show that I found and bought, I really liked and I think I know of someone else that may like it, I would like to buy it for them as a gift but when I open the show I don't see an option to purchase (makes sense since I already bought it), is there a way to do this? I found a way to share it but that just seems to tell someone else that the show exists, I would prefer to send the show to them already purchased as a surprise.
