If you shop Amazon as much as I do, I strongly suggest to get the Amazon Prime membership and you can start it with the 30-Day Prime Video Free Trial. And the best part is now you can download the video to your computer, smartphone or tablet device to watch later. How cool is that?!
By the way, I just watched the Interstellar over the weekend which is a great movie, I give it a 4.5 out of 5 starts.
