This is a great deal. It's 3 movies for $5, how can you complain! All 3 movies are on one double-sided disc (which is one downside) and they're in one standard size dvd case so it saves space on your shelf, which is another plus. A couple more downsides, they don't have any special features, and the quality is like a good VHS. But for the price, it's hard to complain. This is a good set for casual fans of the series, but die-hard fanatics will want the boxset with each film on seperate disc and in seperate cases.
Heads up, there is a previous triple feature like this one with the first 3 films in the series. Same deal, only Part III does come with a short making-of video, the only special feature in the whole set. Walmart doesn't list it online but if you look at your local store you will more than likely find it in the $5 bin, like this set.
