I find that buying boxed sets represent a great saving $$$ over buying each DVD individually. When I buy, I buy the boxed set first. Just buying 1 item cuts down on the 'number of items shipped' cost as well! You can get so many more Anime this way and coupled with Amazon.com's 10-40% discounts, you end up with a larger collection.
