"This is a good place to download Naruto Shippuden videos, if you don't care that much about quality. The episodes are around 100 megabytes or under in size, so you're not getting the best quality video. The site also takes some digging through if you want to find all the episodes in order. On the other hand if you don't know anywhere else to look, this is a good one-stop resource."
"Archive.org hosts episodes of Naruto Shippuden to watch or download. It's a great resource for downloading episodes."
