I was once subscribed to Amazon Prime. I was doing a comparison between Kdrama content offered on that streaming platform versus Viki.com. One thing Amazon did was reward me with a credit for being a loyal customer. Like Viki, Amazon also rents movies and series. But there was Kdrama on my watchlist that I had not watched it because it was a rental. However, I used the Amazon credit and was able to watch the series. Viki might consider giving subscribers credit for being loyal. Just a suggestion.
