What is the best way to Download Battlestar Galactica Episodes? It's a very good and interesting question as there are a few ways you can use to download your favorite TV series. Most of us prefer to use iTunes or Amazon which is a very effective way of downloading TV shows and there's no doubt about it. However, I personally do not think it's the best ways and let me explain why. Every time you download an episode they charge you a fee for it.
